How to find square root?

Divide your number into perfect square factors. This method uses a number’s factors to find a number’s square root (depending on the number, this

Take the square roots of your perfect square factors. The product property of square roots states that for any given numbers a and b, Sqrt (a × b)

Reduce your answer to simplest terms, if your number doesn’t factor perfectly. In real life, more often than not, the numbers you’ll need to find

Estimate, if necessary. With your square root in simplest terms, it’s usually fairly easy to get a rough estimate of a numerical answer by guessing

How do you calculate the square root of a fraction?

To find the square root of a fraction, you first find the square root of the numerator and the denominator. For an example: 4/9 the square root would be 2/3. If the denominator has a square root that is irrational, for example the square root of two, then multiply the numerator and denominator by the irrational number.
