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.
