Best ResponseYou've already chosen the best response.1\[\frac{4\sqrt{400}}{4\sqrt{5}}\] First we can cancel the 4's...since we have a 4 on both top and bottom they will divide to 1 and cancel...so \[\large \frac{\sqrt{400}}{\sqrt{5}}\] Now we know \[\large \frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}\] so now we can write this as \[\large \sqrt{\frac{400}{5}}\] Just do the division and simplify a bit :)
