thats wrong
Apologies for the mistake. Let's reevaluate the expression.
Given that a = -5, we have:
-a^-2 = -(-5)^-2
Now, let's simplify the expression within the parentheses first:
-5^2 = -25
Next, we need to take the reciprocal of -25, which gives us:
-1/25
Therefore, the correct answer is -1/25.
