What is a Square Root?

In mathematics, a square root of a number 'x' is a number 'y' such that y² = x. In simpler terms, it's the value that, when multiplied by itself, gives you the original number. For example, the square root of 9 is 3 because 3 × 3 = 9.

Square roots are fundamental in various fields, from geometry (like finding the side of a square given its area) to physics and computer science. They are used in formulas, equations, and algorithms across many disciplines.

This tool helps you quickly calculate the square root of any non-negative number. Just enter the number, and we'll do the rest! You'll get both the numerical result and a visual representation to help understand the concept better.
