Best ResponseYou've already chosen the best response.1This is how you do it.\[4\sqrt{20}\]Find the greatest factors of 20. \[4\sqrt{4\times5}\]You can take out the 4 from the square root and it will turn into 2. \[4\times 2\sqrt{5}\]Now multiply 4 times 2. \[8\sqrt{5}\]This is in the simplest form it can be.

Best ResponseYou've already chosen the best response.1If you do not know that \(\sqrt{4}=2\) and that \(4*2=8\), I think it would be a good idea to go back and study some old stuff. Else this will not make any sense to you.
