   The exponent of a number says how many times to use the number in a multiplication. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Exponents make it easier to write and use many multiplications. Example: 96 is easier to write and read than 9 × 9 × 9 × 9 × 9 × 9.

   • If N is an integer and is raised to another integer, say ‘a’, then the whole expression, N^a, is the power and a is the exponent.
   • The examples of exponents are: 2 x 2x 2 =2 3 (2 raised to 3rd power) 5x5x5x5 = 5 4 (5 raised to 4th power) 9x9x9x9x9 = 9 5 (9 raised to 5th power)
   • The rules of exponents are: a 0 = 1 a m a n = a m+n a m /a n = a m-n (a m ) n = a mn
   • A negative exponent is used when 1 is divided by repeated multiplication of a factor. Say, 1/n is given by n -1 , where -1 is the exponent. If a nu...
   • If the exponent of a base number is one, then the value of the base remains unchanged. For example, 9 1 = 9 If the exponent is 0, then we get 1 as...
