If the square root is a perfect square, then it would be a rational number. On the other side, if the square root of the number is not perfect, it will be an irrational number. i.e., √10 = 3.16227766017. Examples: Web36. Say 3 is rational. Then 3 can be represented as a b, where a and b have no common factors. So 3 = a 2 b 2 and 3 b 2 = a 2. Now a 2 must be divisible by 3, but then so must a (fundamental theorem of arithmetic). So we have 3 b 2 = ( 3 k) 2 and 3 b 2 = 9 k 2 or even b 2 = 3 k 2 and now we have a contradiction. cac warren county
