Definition of Square Roots

The square root of a number is a value that, when multiplied by itself, gives the original number. It is one of the fundamental operations in mathematics and is denoted by the radical symbol \(\sqrt{}\). For any positive number \(x\), the square root of \(x\) is written as \(\sqrt{x}\), and satisfies the equation:
