Muy bien. La base de esta potencia es negativa, pero como el exponente es par, el resultado de esta operación es un número natural.

Atención, el signo menos no forma parte de la base, entonces, la base es positiva y el resultado de la potencia es positivo, pero el número es negativo, por tanto, no es un número natural.
