You can put this solution on YOUR website!
Go ahead! Your variable is then x^(1/3). You'll find through solution to quadratic formula that x^(1/3) is either 1 or -(1/5). So what then is x?

%28x%5E%281%2F3%29%29%5E3=x

Do that to 1, and you find x=1.
Do that to -(1/5), and find x=%28-%281%2F5%29%29%5E3=?
