Remember that
$\displaystyle \sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}}$
With that in mind you can express
$\displaystyle \sqrt{\frac{5}{12}}$ as $\displaystyle \frac{\sqrt{5}}{\sqrt{12}}$ and solve part c) as you did in parts a) and b)
For part d) you can do something similar, but notice that here we have a cube root.
Try to solve it and let us know if you need more help.
