How do you find the square root of 21? - Answers

21 is not a perfect square, and none of its factors (1, 3, 7, 21) are perfect squares either, so √21 is already simplified. The easiest way to compute an approximate value is using a calculator; if you are familiar with calculus, Newton's method works to find an approximation manually. Either way, it is approximately equal to 4.58258.
