B^2 = what when B = -4
Note: B^2 means B square or B to the second power. The power, in this case 2, tells us how many times to multiply the base B by.
So, B^2 = B • B.
Replace B with -4.
(-4)^2 = (-4)(-4) = 16.
We conclude by saying that B^2 = 16 when B is - 4.
Note: The answer is the same when B is 4.
