WebDivide Square Roots We know that we simplify fractions by removing factors common to the numerator and the denominator. When we have a fraction with a square root in the numerator, we first simplify the square root. Then we can look for common factors. Example 9.60 Simplify: 54 6. Try It 9.119 Simplify: 32 8. Try It 9.120 Simplify: 75 15. northolt levelling upWebWhen we have a fraction with a root in the denominator, like 1/√2, it's often desirable to manipulate it so the denominator doesn't have roots. To do that, we can multiply both the numerator and the denominator by the same root, that will get rid of the root in the denominator. For example, we can multiply 1/√2 by √2/√2 to get √2/2. northolt mandeville councillors
