Descartamos las soluciones complejas:
$$x_{1} = -2$$
Las raíces dadas
$$x_{1} = -2$$
son puntos de cambio del signo de desigualdad en las soluciones.
Primero definámonos con el signo hasta el punto extremo izquierdo:
$$x_{0} < x_{1}$$
Consideremos, por ejemplo, el punto
$$x_{0} = x_{1} - \frac{1}{10}$$
=
$$-2 + - \frac{1}{10}$$
=
$$-2.1$$
lo sustituimos en la expresión
$$\log{\left(x - 2 \right)}^{x} \log{\left(x + 2 \right)}^{x} > 0$$
$$\frac{1}{\log{\left(-2.1 - 2 \right)}^{2.1} \log{\left(-2.1 + 2 \right)}^{2.1}} > 0$$
Entonces
$$x < -2$$
no se cumple
significa que la solución de la desigualdad será con:
$$x > -2$$
$$\log{\left(x - 2 \right)}^{x} \log{\left(x + 2 \right)}^{x} > 0$$
