Answer:
Positive
Step-by-step explanation:
Let's test two even exponent cases
Lets take negative two and raise it to by two as an exponent.
-2 * -2 = 4 (a positive number)
Now lets take negative two and raise it to by four as an exponent.
-2*-2*-2*-2 = 16 (a positive number)
Even though this is not a formal mathematical proof, it at least shows that the rule seems to hold for these two cases and other even exponents actually.
