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] For example, 4 and −4 are square roots of 16 because 4 2 = ( − 4 ) 2 = 16 {\displaystyle 4^{2}=(-4)^{2}=16} .
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.
A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16.
Square Root Definition. 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.
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.
10 Οκτ 2024 · A square root of is a number such that . When written in the form or especially , the square root of may also be called the radical or surd. The square root is therefore an n th root with . Note that any positive real number has two square roots, one positive and one negative. For example, the square roots of 9 are and , since .
