Detailed explanation-1: -The ‘nth root’ of a number is a number that multiplied by itself ‘n’ times to get the initial value. nth roots are represented by the symbol n√. To find the nth root of a number we have to find that number, whose ‘n’ times multiplication by itself gives the number for which we have to find the nth root.
Detailed explanation-2: -The principal nth root of a is written as n√a, where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.
Detailed explanation-3: -We say that x is a nth root of a if xn = a. It is easy to show that if a has an nth root, then this root is unique. This follows from the fact that if x and y are positive numbers for which xn = yn, then x = y. The nth root of a is denoted by n √a.
