Example : 1) 6 x 6 x 6 x 6 x 6 x 6 x 6 , here there is a multiplication of 6 and 6 is repeated 7 times so this can be written in shortest way as 6

So 6 x 6 x 6 x 6 x 6 x 6 x 6 = 6

and its value is 279,936.

2) 5 x 5 x 5 x 5 = 5

In general, in a

This process of using ex-ponents is called "raising to a power", where the ex-ponent is the "power". The expression "5

There are two specially-named powers: "to the second power" is generally pronounced as "squared", and "to the third power" is generally pronounced as "cubed". So "5

In general we can say that , a

3) b x b x b x a x a

= b

4) (ab) x (ab) x (ab) x (ab)

5) (4/3)x (4/3) x (4/3) x (4/3)
