Question

can someone help me find the four solutions to this equation?

Answer 1

\[y ^{4}-256=0\]

Answer 2

Well you start by putting y on one side and 256 on the other

Answer 3

and then what?

Answer 4

Well what did you get, write it on the screen

Answer 5

I actually don't know exactly what that's supposed to look like. Do I just add 256 to one side?

Answer 6

Yes.

Answer 7

so \[y ^{4}=256\]

Answer 8

now take the 4th root of both sides

Answer 9

(y^4-16^2)=(y^2-16)(y^2+16)
(y-4)(y-4)(y^2+16)
