Question

Evaluate A^2(-B^2) for A = 4 and B = -5.
A. -26
B. -9
C. 41

Answer 1

A^2(-B^2) for A = 4 and B = -5


A^2(-B^2) =

= 4^2 * [-(-5)^2]

= 16 * (-25)

= -400

The correct answer to the question you asked is not in the choices.

Maybe you copied it incorrectly, and you meant

A^2-B^2 for A = 4 and B = -5,


in which case it's


4^5 - 5^2 = 16 - 25 = -9
