What have you tried? \[\sqrt[3]{x} \implies x^{1/3}\]

OpenStudy (omarbirjas):

@iambatman Yea, but all i get it an even more complicated answer...Can you take me step by step? I think I may have made a mistake....

@jdoe0001

OpenStudy (jdoe0001):

simplifying right?

OpenStudy (jdoe0001):

lemme do as iambatman suggested, let us use rational exponents one sec

OpenStudy (omarbirjas):

Finally somebody willing to help. I've been at this thing all day.... @jdoe0001

OpenStudy (jdoe0001):

hold the mayo
