Solución detallada
Tenemos la ecuación
$$\frac{\log{\left(u^{2} + 1 \right)}}{2} - \operatorname{atan}{\left(u \right)} = \log{\left(c \right)} - \log{\left(x \right)}$$
Transpongamos la parte derecha de la ecuación miembro izquierdo de la ecuación con el signo negativo
$$\log{\left(x \right)} = \log{\left(c \right)} - \frac{\log{\left(u^{2} + 1 \right)}}{2} + \operatorname{atan}{\left(u \right)}$$
Es la ecuación de la forma:
log(v)=p

Por definición log
v=e^p

entonces
$$x = e^{\frac{\log{\left(c \right)} - \frac{\log{\left(u^{2} + 1 \right)}}{2} + \operatorname{atan}{\left(u \right)}}{1}}$$
simplificamos
$$x = \frac{c e^{\operatorname{atan}{\left(u \right)}}}{\sqrt{u^{2} + 1}}$$
