Math Help - Dividing Radicals #2

imgur: the simple image sharer

I have done the first 2 questionf of 8 but I cannot do the last 2,

I don't know what to do so I haven't attempted anything...

Remember that

$\sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}}$

With that in mind you can express

$\sqrt{\frac{5}{12}}$ as $\frac{\sqrt{5}}{\sqrt{12}}$ 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.
