(-2)² =
-2³ =
(-2)³ =

Explanation:

Exponent first, then negative sign: $- (2^2) = -4$

Step2: Evaluate $(-2)^2$

Square the negative number: $(-2) \times (-2) = 4$

Step3: Evaluate $-2^3$

Exponent first, then negative sign: $- (2^3) = -8$

Step4: Evaluate $(-2)^3$

Cube the negative number: $(-2) \times (-2) \times (-2) = -8$
