Answer 6

when you break it down and there is two groups of 2 do you just do 2(2)?

Answer 7

@satellite73 gave you a very big hint at ow to solve this.
you need to make use of the rule \(\sqrt{a\times b}=\sqrt{a}\times\sqrt{b}\).
so, in your case, we have \(\sqrt{240}=\sqrt{16\times15}=\sqrt{16}\times\sqrt{15}=4\times\sqrt{15}=4\sqrt{15}\)
