• Root, in mathematics, a solution to an equation, usually expressed as a number or an algebraic formula.In the 9th century, Arab writers usually called one of the equal factors of a number jadhr (“root”), and their medieval European translators used the Latin word radix (from which derives the adjective radical). If a is a positive real number and n a positive integer, there exists a unique positive real number x such that xn = a.
• This number—the (principal) nth root of a—is written nSquare root of√ a or a1/n. The integer n is called the index of the root. For n = 2, the root is called the square root and is written Square root of√ a . The root 3Square root of√ a is called the cube root of a. If a is negative and n is odd, the unique negative nth root of a is termed principal. For example, the principal cube root of –27 is –3.
