    well; you take out as many perfect squares as you can and convert them to their integer counterparts then

    perfect squares are 1,4,9,16,25,36,49,64,81,etc

    does 8 have a perfect square that we can factor out of it?

    are you sure? I would assume that 4 * 2 = 8 ... and that 4 is a perfect square

    sqrt(4) * sqrt(2) = 2sqrt(2) would you agree?

    the bottom is a perfect square: sqrt(16) = 4 right? so we simplify it as.... 2sqrt(2) sqrt(2) ------ which can be simplified further to ------; do you agree? 4 2
