Square root - Wikipedia. Notation for the (principal) square root of x. For example, √ 25 = 5, since 25 = 5 ⋅ 5, or 52 (5 squared). 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. [1] .
In Maths, the square root of a number produces the original number when multiplied by itself. Learn how to find square roots, square root symbol, formulas, table, etc., only at BYJU’S.
It is easy to work out the square root of a perfect square, but it is really hard to work out other square roots. Example: what is √10? Well, 3 × 3 = 9 and 4 × 4 = 16, so we can guess the answer is between 3 and 4.
The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number. It is represented using the symbol '√ '. The square root symbol is called a radical, whereas the number under the square root symbol is called the radicand.
Taking the square root is figuring out what number multiplied by itself is equal to the number under the square root symbol. So: √4 = 2, because 2*2 OR 2^2 = 4

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.
