    Please show your working .

    Just to get you started,
    Let x^1/3 = t .
    dx = 3x^(2/3)dt = 3t^2dt

    Can you go from here ?

    How did you go from dx = 3x^(2/3)dt to 3t^2dt

    Ok I think I get what to do next, substiture dx into the orignal equation?

    [tex]dx = 3x^{\frac{2}{3}} dt=3\left( x^{\frac{1}{3}}\right) ^{2} = 3t^2dt[/tex]
