**Definition of Indices**

A number or a variable may have an index. Index of a variable (or a constant) is a value that is raised to the power of the variable. The indices are also known as **powers or exponents**. It shows the number of times a given number has to be multiplied. It is represented in the form:

**a ^{m }= a × a × a ×……× a (m times)**
