Solución

Ha introducido [src]
log(1 + x)*log(3) = log(t)
$$\log{\left(3 \right)} \log{\left(x + 1 \right)} = \log{\left(t \right)}$$
Solución detallada
Tenemos la ecuación
$$\log{\left(3 \right)} \log{\left(x + 1 \right)} = \log{\left(t \right)}$$
Transpongamos la parte derecha de la ecuación miembro izquierdo de la ecuación con el signo negativo
$$- \log{\left(t \right)} = - \log{\left(3 \right)} \log{\left(x + 1 \right)}$$
Devidimos ambás partes de la ecuación por el multiplicador de log =-1
$$\log{\left(t \right)} = \log{\left(3 \right)} \log{\left(x + 1 \right)}$$
Es la ecuación de la forma:
log(v)=p

Por definición log
v=e^p

entonces
$$t = e^{\frac{\left(-1\right) \log{\left(3 \right)} \log{\left(x + 1 \right)}}{-1}}$$
simplificamos
$$t = e^{\log{\left(3 \right)} \log{\left(x + 1 \right)}}$$
