Solución
Solución detallada
Tenemos la ecuación
$$z^{3} = 1 - \sqrt{3 i}$$
Ya que la potencia en la ecuación es igual a = 3 - no contiene número par en el numerador, entonces
la ecuación tendrá una raíz real.
Extraigamos la raíz de potencia 3 de las dos partes de la ecuación:
Obtenemos:
$$\sqrt[3]{z^{3}} = \sqrt[3]{1 - \sqrt{3} \sqrt{i}}$$
o
$$z = \sqrt[3]{1 - \sqrt{3} \sqrt{i}}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
Obtenemos la respuesta: z = (1 - sqrt(3)*sqrt(i))^(1/3)
Las demás 3 raíces son complejas.
hacemos el cambio:
$$w = z$$
entonces la ecuación será así:
$$w^{3} = 1 - \sqrt{3} \sqrt{i}$$
Cualquier número complejo se puede presentar que:
$$w = r e^{i p}$$
sustituimos en la ecuación
$$r^{3} e^{3 i p} = 1 - \sqrt{3} \sqrt{i}$$
donde
$$r = \sqrt[6]{- \frac{\sqrt{6}}{2} + 1 - \frac{3 \sqrt{2} \sqrt{i} i}{2} - \sqrt{3} \sqrt{i} + \frac{\sqrt{6} i}{2} + \frac{3 \sqrt{2} \sqrt{i}}{2}}$$
- módulo del número complejo
Sustituyamos r:
$$e^{3 i p} = \frac{1 - \sqrt{3} \sqrt{i}}{\sqrt{- \frac{\sqrt{6}}{2} + 1 - \frac{3 \sqrt{2} \sqrt{i} i}{2} - \sqrt{3} \sqrt{i} + \frac{\sqrt{6} i}{2} + \frac{3 \sqrt{2} \sqrt{i}}{2}}}$$
Usando la fórmula de Euler hallemos las raíces para p
$$i \sin{\left(3 p \right)} + \cos{\left(3 p \right)} = \frac{1 - \sqrt{3} \sqrt{i}}{\sqrt{- \frac{\sqrt{6}}{2} + 1 - \frac{3 \sqrt{2} \sqrt{i} i}{2} - \sqrt{3} \sqrt{i} + \frac{\sqrt{6} i}{2} + \frac{3 \sqrt{2} \sqrt{i}}{2}}}$$
es decir
$$\cos{\left(3 p \right)} = \frac{1 - \frac{\sqrt{6}}{2}}{\sqrt{4 - \sqrt{6}}}$$
y
$$\sin{\left(3 p \right)} = - \frac{\sqrt{6}}{2 \sqrt{4 - \sqrt{6}}}$$
entonces
$$p = \frac{2 \pi N}{3} - \frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3}$$
donde N=0,1,2,3,...
Seleccionando los valores de N y sustituyendo p en la fórmula para w
Es decir, la solución será para w:
$$w_{1} = \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)} - i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}$$
$$w_{2} = - \frac{\sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{\sqrt{3} \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{\sqrt{3} i \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2}$$
$$w_{3} = - \frac{\sqrt{3} \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} - \frac{\sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} - \frac{\sqrt{3} i \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2}$$
hacemos cambio inverso
$$w = z$$
$$z = w$$
Entonces la respuesta definitiva es:
$$z_{1} = \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)} - i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}$$
$$z_{2} = - \frac{\sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{\sqrt{3} \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{\sqrt{3} i \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2}$$
$$z_{3} = - \frac{\sqrt{3} \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} - \frac{\sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} - \frac{\sqrt{3} i \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2}$$
$$z^{3} = 1 - \sqrt{3 i}$$
Ya que la potencia en la ecuación es igual a = 3 - no contiene número par en el numerador, entonces
la ecuación tendrá una raíz real.
Extraigamos la raíz de potencia 3 de las dos partes de la ecuación:
Obtenemos:
$$\sqrt[3]{z^{3}} = \sqrt[3]{1 - \sqrt{3} \sqrt{i}}$$
o
$$z = \sqrt[3]{1 - \sqrt{3} \sqrt{i}}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
z = 1+sqrt+3sqrti)^1/3
Obtenemos la respuesta: z = (1 - sqrt(3)*sqrt(i))^(1/3)
Las demás 3 raíces son complejas.
hacemos el cambio:
$$w = z$$
entonces la ecuación será así:
$$w^{3} = 1 - \sqrt{3} \sqrt{i}$$
Cualquier número complejo se puede presentar que:
$$w = r e^{i p}$$
sustituimos en la ecuación
$$r^{3} e^{3 i p} = 1 - \sqrt{3} \sqrt{i}$$
donde
$$r = \sqrt[6]{- \frac{\sqrt{6}}{2} + 1 - \frac{3 \sqrt{2} \sqrt{i} i}{2} - \sqrt{3} \sqrt{i} + \frac{\sqrt{6} i}{2} + \frac{3 \sqrt{2} \sqrt{i}}{2}}$$
- módulo del número complejo
Sustituyamos r:
$$e^{3 i p} = \frac{1 - \sqrt{3} \sqrt{i}}{\sqrt{- \frac{\sqrt{6}}{2} + 1 - \frac{3 \sqrt{2} \sqrt{i} i}{2} - \sqrt{3} \sqrt{i} + \frac{\sqrt{6} i}{2} + \frac{3 \sqrt{2} \sqrt{i}}{2}}}$$
Usando la fórmula de Euler hallemos las raíces para p
$$i \sin{\left(3 p \right)} + \cos{\left(3 p \right)} = \frac{1 - \sqrt{3} \sqrt{i}}{\sqrt{- \frac{\sqrt{6}}{2} + 1 - \frac{3 \sqrt{2} \sqrt{i} i}{2} - \sqrt{3} \sqrt{i} + \frac{\sqrt{6} i}{2} + \frac{3 \sqrt{2} \sqrt{i}}{2}}}$$
es decir
$$\cos{\left(3 p \right)} = \frac{1 - \frac{\sqrt{6}}{2}}{\sqrt{4 - \sqrt{6}}}$$
y
$$\sin{\left(3 p \right)} = - \frac{\sqrt{6}}{2 \sqrt{4 - \sqrt{6}}}$$
entonces
$$p = \frac{2 \pi N}{3} - \frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3}$$
donde N=0,1,2,3,...

Es decir, la solución será para w:
$$w_{1} = \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)} - i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}$$
$$w_{2} = - \frac{\sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{\sqrt{3} \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{\sqrt{3} i \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2}$$
$$w_{3} = - \frac{\sqrt{3} \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} - \frac{\sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} - \frac{\sqrt{3} i \sqrt[6]{4 - \sqrt{6}} \cos{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2} + \frac{i \sqrt[6]{4 - \sqrt{6}} \sin{\left(\frac{\operatorname{atan}{\left(\frac{\sqrt{6}}{2 \left(1 - \frac{\sqrt{6}}{2}\right)} \right)}}{3} + \frac{\pi}{3} \right)}}{2}$$
