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, a square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3, because 3 * 3 = 9.

The square root symbol is √, also known as the radical symbol. For instance, √9 represents the square root of 9. This calculator computes the principal square root, which is the non-negative root.

Square roots are fundamental in various fields, including geometry (like finding the side of a square given its area), physics, and computer science. They are also essential in more advanced mathematical concepts and problem-solving.
