Answer:
8
Step-by-step explanation:
Expression:
(-B)2
Let's substitute the value of B into this expression:
B = -4
(-B)2
[-(-4)]2
Notice how there are two negative signs int this expression:
[-(-4)]2
Well, there is an invisible 1 behind the first negative sign.
[-(-4)]2
[-1(-4)]2
All we have to do now is multiply:
[-1(-4)]2
(4)2
(4)2
= 8
Therefore, the value of the expression is 8.
