In mathematics, a radical, also known as a root, is a symbol represented by the square root (√) or cube root (∛) and can be either a square root or a cube root, among others
. The number or expression inside the radical symbol is called the radicand
. The radical symbol is used to denote square root or nth roots
. For example, in the expression x\sqrt{x}x, 'x' is the radicand, and the symbol (√) represents the square root
. The radical can describe different kinds of roots for a number, such as square root, cube root, fourth root, and so on
. The index number or degree, which is a whole number, is represented before the radical symbol
. Radicals are used in various fields, including construction, where they help determine the amount of materials needed for a project
. They can be solved using various rules and formulas, depending on the type of radical expression
