**As we all know and discussed earlier that, when a number multiplied by itself repeatedly then the number of repetitions is called a Power or Exponential of the number. The number is called the ‘Base’ of the power and the number of times it is multiplied is called the ‘Exponent’ or ‘Index’.**

**The product a x a should be written as a² (here ‘a’ is multiplied by 2 times ) is a power of ‘a’, here the base is ‘a’ and the index is 2. Similarly b x b x b x b should be written as b⁴ and here ‘b’ is the base and 4 is the power or index of ‘b’ because ‘b’ is multiplied by 4 times. **

**For your better understanding, we are giving some example below**

**7 x 7 x 7 x 7 x 7 = 7⁵, where 7 is the base and 5 is the index or power of 7 **

**9 x 9 x 9 x 9 x 9 x 9 = 9⁶, where 9 is the base and 6 is the index or power of 9**
