Hello there!
Evaluate a² for a = -4
The first step we need to do is replace a by -4
So we have (-4)²
Now what you have realize is that we need to multiply -4 by itself twice.
So it should looks like this:
-4 * -4
The rules says that when we have minus * minus, the answer is positive.
So we have -4 * -4 = 16
Answer: 16
I hope this helps!
