Answer:
Step-by-step explanation:
(-2)² = 4 and -2² = -4.
In the first case, exponentiation must be done first; we get (-2)².
In the second case, 2² must be evaluated first; the result is 4. Then
-2² = -4 (different from the 4 obtained above). Here exponentiation must be carried out before multiplication by -1.
