Question 121193: May I please have some help solving this equation?
Find all solutions of the equation below. (If there are more answer boxes than answers, enter NONE.)
x^4 - 256 = 0
Answer by stanbon(75887) About Me  (Show Source):
You can put this solution on YOUR website!
x^4 - 256 = 0
Factor:
(x^2-16)(x^2+16) = 0
(x-4)(x+4)(x+4i)(x-4i)=0
x = 4 or -4 or -4i or 4i
