Now the square root of 25 is 5 and the square root of 100 is 10. So, the answer is 5/10 or 1/2. Not sure what about the next statement unless you meant .2 raised to the second power. In that case, the answer would be .2 x .2 = .04 or you could write: 2 x 2 4 1 ---- --- = --- = --- 10 10 100 25 Hope that helps.
