    You will need to break the square root up. To do this find two numbers that when multiplied together give 92 and one of those numbers has to be a perfect square (a number that can be square rooted and leave no remainder):

    √92

    = √4 x √23

    = 2 x √23

    = 2√23

    That is in it's simplest form as there are no two numbers that when multiplied together give 23 and one of the numbers are a perfect square. It would really help to memorise the perfect square table.

    √ 92 = √ (4 x 23) = √4 √23 = 2√23
