Square Roots | Brilliant Math & Science WikiThe 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.

Square root - Math.netA 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. We can also write this as "z raised to the power of 2 is equal to x" as follows: z 2 = x.

Square Root -- from Wolfram MathWorldA square root of x is a number r such that r^2=x. When written in the form x^(1/2) or especially sqrt(x), the square root of x may also be called the radical or surd. The square root is therefore an nth root with n=2. Note that any positive real number has two square roots, one positive and one negative. For example, the square roots of 9 are ...
