El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
Solución detallada
Tenemos la ecuación:
$$\log{\left(\frac{1}{3} \right)}^{x} = 3$$
o
$$\log{\left(\frac{1}{3} \right)}^{x} - 3 = 0$$
o
$$\left(- \log{\left(3 \right)}\right)^{x} = 3$$
o
$$\left(- \log{\left(3 \right)}\right)^{x} = 3$$
- es la ecuación exponencial más simple
Sustituimos
$$v = \left(- \log{\left(3 \right)}\right)^{x}$$
obtendremos
$$v - 3 = 0$$
o
$$v - 3 = 0$$
Transportamos los términos libres (sin v)
del miembro izquierdo al derecho, obtenemos:
$$v = 3$$
Obtenemos la respuesta: v = 3
hacemos cambio inverso
$$\left(- \log{\left(3 \right)}\right)^{x} = v$$
o
$$x = \frac{\log{\left(v \right)}}{\log{\left(\log{\left(3 \right)} \right)} + i \pi}$$
Entonces la respuesta definitiva es
$$x_{1} = \frac{\log{\left(3 \right)}}{\log{\left(- \log{\left(3 \right)} \right)}} = \frac{\log{\left(3 \right)}}{\log{\left(\log{\left(3 \right)} \right)} + i \pi}$$
log(3)*log(log(3)) pi*I*log(3)
x1 = ------------------ - ------------------

pi + log (log(3)) pi + log (log(3))
$$x_{1} = \frac{\log{\left(3 \right)} \log{\left(\log{\left(3 \right)} \right)}}{\log{\left(\log{\left(3 \right)} \right)}^{2} + \pi^{2}} - \frac{i \pi \log{\left(3 \right)}}{\log{\left(\log{\left(3 \right)} \right)}^{2} + \pi^{2}}$$
x1 = log(3)*log(log(3))/(log(log(3))^2 + pi^2) - i*pi*log(3)/(log(log(3))^2 + pi^2)
