Answer:
4. +4 , -4
Step-by-step explanation:
I did number 4 and 6 instead.
4. x^{2} +32=16
do opposite of +32 to even out equation, so subtract 32 from 16, 16-32= -16
no u have x^2 = -16
to get rid of the exponent we must do the opposite of it, a square root, to both sides. so the square root of -16 is x= +4 or -4
