Square Root Function

The square root function finds a number that, when multiplied by itself, equals a given value. For example, the square root of 16 is 4 because 4 × 4 = 16. It's represented as √x, where x is the number under the square root symbol. This function provides a way to reverse squaring a number. Square roots are used in various fields like geometry, physics, and engineering to solve problems involving areas, distances, and other measurements. Most numbers have both positive and negative roots, but in many contexts, we focus on the positive one.
