Best ResponseYou've already chosen the best response.0you have one term that is √45 √45 = √(3 * 3 * 5) = √(3^2 * 5) = √3^2 * √5 = 3 * √5

Best ResponseYou've already chosen the best response.0because √x^2 = x and √(x * y) = √x * √y

Best ResponseYou've already chosen the best response.0nick, i would go with welsh drawing lol yours looks kinda complicated. \[45=3*3*5\]\[\sqrt{45}=\sqrt{9}\sqrt{5}=3\sqrt{5}\]
