Answer 3

First, you find the largest perfect square that is a factor of 180. This website is great for that ( http://www.mathwarehouse.com/arithmetic/numbers/list-of-perfect-squares.php). Since 36 is the highest perfect square that goes in 180 you use that and can rewrite the equation as 4 * √36 * √5 and then simplify this to 4 * 6 √5 and then one last time to 24 √5
