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 mathematics, a square root function is defined as a one-to-one function that takes a positive number as an input and returns the square root of the given input number. f (x) = √x. For example, if x=4, then the function returns the output value as 2. Note: The square root of a negative number represents a complex number.
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.
