In mathematics, a square root of a number x is a number y such that =; in other words, a number y whose square (the result of multiplying the number by itself, or ) is x. For example, 4 and −4 are square roots of 16 because = =.
The square root of a number \(a\), denoted \(\sqrt{a}\), is the number \(b\) such that \[b^{2} = a\text{ and }b\ge 0.\] The square root symbol "\(\sqrt{\ }\)" is also sometimes called a radical. The number or expression underneath the top line of the square root symbol is called the radicand.
A square root is a number that can be multiplied by itself to give us the value under the radical symbol (also referred to as the radix). A square root is denoted as follows: In the figure above, z is the square root of x.
The square root of a number is the factor that we can multiply by itself to get that number. The symbol for square root is 1 .
