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
