What are Exponents?

• An exponent refers to the number of times a number is multiplied by itself.
• If a number A is multiplied by itself n times, then it is written as An and it is read as

‘A raised to the power of n’ or the ‘nth power of A’.

• Here A is called the Base and n is called the Exponent.

For example,

3 x 3 x 3 x 3 x 3 x 3 x 3 = 3⁷.

Here 3 is the base and the exponent is 7.

It is read as ‘3 raised to the power of 7’ or ‘seventh power of 3’.
