an is a short hand way of writing

a x a x a ……. (n factors)

a is called the base number

and n is called the index number

Indices

x 2 x 2

Calculate : 23 x 22

2 x 2 x 2

= 32

Calculate : 25

= 32

Can you spot the connection !

4 x 4 x 4

= 4

Indices

÷ 4 x 4

Calculate : 43÷ 42

Calculate : 41

= 4

Can you spot the connection !

am x an = a(m + n)simply add powers

am÷ an = a(m - n)simply subtract powers
