Question 1833
I am not too sure of the proper answer to this, but i have just messed around with it...look at prime numbers, eg 2, 3, 4, 5, 7, 11 etc

Start with 2 and divide 576 by 2, to give 288x2. Now do it again on the 288 to give 144x2x2. Now spot that 144 is 12x12, so we have:

576 = 12x12x2x2
or
576 = (12x2)x(12x2)
576 = 24x24

therefore the positive square root of 576 is 24
