Solución detallada
Tenemos la ecuación
$$z^{8} = 3 + 3 i$$
Ya que la potencia en la ecuación es igual a = 8 y miembro libre = 3 + 3*i complejo,
significa que la ecuación correspondiente no tiene soluciones reales
Las demás 8 raíces son complejas.
hacemos el cambio:
$$w = z$$
entonces la ecuación será así:
$$w^{8} = 3 + 3 i$$
Cualquier número complejo se puede presentar que:
$$w = r e^{i p}$$
sustituimos en la ecuación
$$r^{8} e^{8 i p} = 3 + 3 i$$
donde
$$r = \sqrt[16]{2} \sqrt[8]{3}$$
- módulo del número complejo
Sustituyamos r:
$$e^{8 i p} = \frac{\sqrt{2} \left(3 + 3 i\right)}{6}$$
Usando la fórmula de Euler hallemos las raíces para p
$$i \sin{\left(8 p \right)} + \cos{\left(8 p \right)} = \frac{\sqrt{2} \left(3 + 3 i\right)}{6}$$
es decir
$$\cos{\left(8 p \right)} = \frac{\sqrt{2}}{2}$$
y
$$\sin{\left(8 p \right)} = \frac{\sqrt{2}}{2}$$
entonces
$$p = \frac{\pi N}{4} + \frac{\pi}{32}$$
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:
$$w_{1} = - \sqrt[16]{2} \sqrt[8]{3} \sin{\left(\frac{\pi}{32} \right)} + \sqrt[16]{2} \sqrt[8]{3} i \cos{\left(\frac{\pi}{32} \right)}$$
$$w_{2} = \sqrt[16]{2} \sqrt[8]{3} \sin{\left(\frac{\pi}{32} \right)} - \sqrt[16]{2} \sqrt[8]{3} i \cos{\left(\frac{\pi}{32} \right)}$$
$$w_{3} = - \sqrt[16]{2} \sqrt[8]{3} \cos{\left(\frac{\pi}{32} \right)} - \sqrt[16]{2} \sqrt[8]{3} i \sin{\left(\frac{\pi}{32} \right)}$$
$$w_{4} = \sqrt[16]{2} \sqrt[8]{3} \cos{\left(\frac{\pi}{32} \right)} + \sqrt[16]{2} \sqrt[8]{3} i \sin{\left(\frac{\pi}{32} \right)}$$
$$w_{5} = - \frac{2^{\frac{9}{16}} \sqrt[8]{3} \sin{\left(\frac{\pi}{32} \right)}}{2} + \frac{2^{\frac{9}{16}} \sqrt[8]{3} \cos{\left(\frac{\pi}{32} \right)}}{2} + \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \sin{\left(\frac{\pi}{32} \right)}}{2} + \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \cos{\left(\frac{\pi}{32} \right)}}{2}$$
$$w_{6} = \frac{2^{\frac{9}{16}} \sqrt[8]{3} \sin{\left(\frac{\pi}{32} \right)}}{2} + \frac{2^{\frac{9}{16}} \sqrt[8]{3} \cos{\left(\frac{\pi}{32} \right)}}{2} - \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \cos{\left(\frac{\pi}{32} \right)}}{2} + \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \sin{\left(\frac{\pi}{32} \right)}}{2}$$
$$w_{7} = - \frac{2^{\frac{9}{16}} \sqrt[8]{3} \cos{\left(\frac{\pi}{32} \right)}}{2} - \frac{2^{\frac{9}{16}} \sqrt[8]{3} \sin{\left(\frac{\pi}{32} \right)}}{2} - \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \sin{\left(\frac{\pi}{32} \right)}}{2} + \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \cos{\left(\frac{\pi}{32} \right)}}{2}$$
$$w_{8} = - \frac{2^{\frac{9}{16}} \sqrt[8]{3} \cos{\left(\frac{\pi}{32} \right)}}{2} + \frac{2^{\frac{9}{16}} \sqrt[8]{3} \sin{\left(\frac{\pi}{32} \right)}}{2} - \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \cos{\left(\frac{\pi}{32} \right)}}{2} - \frac{2^{\frac{9}{16}} \sqrt[8]{3} i \sin{\left(\frac{\pi}{32} \right)}}{2}$$
hacemos cambio inverso
$$w = z$$
$$z = w$$
Entonces la respuesta definitiva es:
$$z_{1} = - \sqrt[16]{2} \sqrt[8]{3} \sin{\left(\frac{\pi}{32} \right)} + \sqrt[16]{2} \sqrt[8]{3} i \cos{\left(\frac{\pi}{32} \right)}$$
