Short Answer

Expert verified

The $n^{t h}$ root of a number $x$ is a number $r$ which, if raised to a power $n$ , gives $x$ .

Step by step solution

Step 1. Explanation

A root is the solution to the equation, usually represented as an algebraic expression or formula.

The $n^{t h}$ root of a number $x$ , usually a positive number, is a number which when raised to power $n$ , gives $x$ .

Step 2. Example

For example.

Let's assume a number $125$ .

We know that ${(5)}^{3} = 125$ .

So we can say that $5$ is third root or cube root of $125$ .
