Um, if you don't know then you can move along. XD You don't have to let me know that you don't know. :P

Ok, there are a couple ways to go about this, but if you notice, $$\sqrt{36}*\sqrt{20}=\sqrt{720}$$
From there you can also get $$\sqrt{4}*\sqrt{5}=\sqrt{20}$$
So $$6*2*\sqrt{5}=\sqrt{720}$$
6*2=12 so the final result is$$12\sqrt{5}$$

Nope, 12 is the lowest you can go. We know this because we have simplified the square root side as far as it can go.
