Ignore the fraction for a second. Turn ∛(x⁴) into a single indice.

Once you've done that, you need to use the common technique you use when you have an indice on the denominator.

And thats it. Any more help needed, just post it below!

Thats the first step done. You can simplify it further. Hint: 1/x = x^(-1)

When you have a power on the bottom, you can simply bring it to the top and change the sign.

For example: \frac{1}{x^2} = x^-2

So in your case: \frac{2}{x^4/3} = 2x^-\frac{4}{3}
