Solución

Ha introducido [src]
   x         
log (1/3) = 3
$$\log{\left(\frac{1}{3} \right)}^{x} = 3$$
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
$$x_{1} = \frac{\log{\left(3 \right)}}{\log{\left(- \log{\left(3 \right)} \right)}} = \frac{\log{\left(3 \right)}}{\log{\left(\log{\left(3 \right)} \right)} + i \pi}$$
