Question

I need help on how to to square out the cube in this problem. (x+2)^3= -27

Answer 1

ok you want to take the cube root to get rid of the cube
(x+2)=(-27)^(1/3)

Answer 2

Oh, then what would I do from there?

Answer 3

x+2=[(-3)(-3)(-3)]^(1/3)
x+2=-3
x=-3-2=-5
check:
x=-5
(x+2)^3=-27
(-5+2)^3=-27
(-3)^3=-27
-27=-27

Answer 4

Oh =O I see now. Thank you ^^
