Before we learn to calculate it, it’s important to understand what it really means, how we calculate it normally. Quick Intro: Calculating a square root is an inverse calculation for coming back to the root of a square. So, when you calculate the square of 10 by multiplying it with its self, that’s (10 * 10 = 100).
For a larger number, you could find the square root using prime factorization. For example, to find the square root of 2,000, you could find the square roots of 500 and 4, which are multiplied together to equal 2,000. The square root of 4 is 2, and the square root of 500 is 5 times the square root of 20, which is 10 times the square root of 5.
