Answer 2

You find two numbers whos product is your surd. Trying to get one factor to be the square of a number. For example if you want to simplify a surd of 75 you would choose 25x3. you write it by using square root symbol(srs) in front of (25x3)= srs 25x srs 3 which equals 5x(srs)3 written the same without x. I am sorry this looks so confusing but my computer does not have a srs square root symbol.
