How does dividing radicals work?

Question

Here I have the problem $\dfrac{5\sqrt{24}\cdot 3\sqrt{45}}{\sqrt{6}}$. Not sure how to actually type it out here. How do I actually solve it? The answer says $90\sqrt{5}$ but how?

Answer 1

$\sqrt{24} = 2\sqrt{6}$, and $\sqrt{45} = 3\sqrt{5}$, from this the answer follows.
