Solución detallada
Tenemos la ecuación
$$\log{\left(u - 1 \right)} = \frac{\frac{1}{2} \left(x^{2} - 4 x\right)}{2}$$
$$\log{\left(u - 1 \right)} = \frac{x^{2}}{4} - x$$
Es la ecuación de la forma:
log(v)=p
Por definición log
v=e^p
entonces
$$u - 1 = e^{\frac{\frac{x^{2}}{4} - x}{1}}$$
simplificamos
$$u - 1 = e^{\frac{x^{2}}{4} - x}$$
$$u = e^{\frac{x^{2}}{4} - x} + 1$$
