Seperate the constants - you get:
2x = -3
Divide both sides by 2
x = -3/2
take the cube root of -3/2
Its an irrational about -1.2599

cbrt(2x-2) -a million = -5 cbrt(2x-2) = -4 2x-2 = (-4)³ 2x = -sixty 4+2 x = -sixty 2/2 x = -31 in case you propose: cbrt[(2x-2) -a million] = -5 (2x-2) -a million = (-5)³ 2x-2 = -one hundred twenty 5+a million 2x = -124+2 x = -122/2 x = -sixty one

You and your math questions writergirl.
We here at Yahoo Answers really shouldn't be doing your math homework for you. Now I realize that is a rather hard line to take but you kids need to learn the hard way that people aren't always going to be there to give you the answers in life.
ps. Have you tried looking for the answers in the back of the book?

First, cube each side of the equation, giving you 2x+1 = -8
Then subtract one from each side, giving you 2x = -9
Then divide each side by 2, giving you x = -9/2

cube root of 2x+1 = -2
cube both sides: 2x+1 = -8
solve:
2x = -9
x = -(9/2)

you subtract 1 from both sides and you get 2x= negative 3
then you divide both sides by 2 and get negative 3/2
