This might be a trivial question. I am a Sage newbie. I have figured out so far how to get sage to solve equations like:

x==y^2 for y (answer - y=sqrt(x) x==y^3 for y (answer - y=x^(1/3)

But i cant get sage to solve x==y^(1/3) for example....essentially where the power is not an integer....possible ?

Thanks

You may need to give it some assumptions. For example, the following will solve your equation.

var('x,y')
assume(x>0)
solve(x==y^(1/3),y)
