1. Multiplying Exponents Powers with the Same Base
How could you write
6 x 6 x 6 x 6
as a power?
How could you write
6 x 6 x 6
as a power?
So how do you think you could write
(6 x 6 x 6 x 6) x (6 x 6 x 6)
as a power?
So if we write that using powers only
1

2. Multiplication of powers with the same
base
The rule
(am)(an) = am+n
Which reads when you multiply two
powers with the same base
Keep the base and add the
exponents
Example
114 x 112 = 114+2 = 116
Examples write each as a single power
a)
b)
c)
2

3. What do you get when you
Divide as repeated multiplication Divide as powers
2 x 2 x 2 x 2 x 2 x 2 x 2 27
by by
2 x 2 x 2 23
3

4. Dividing Powers Rule
am
an = am÷ an = am­n
When you divide a power by a power and they have the
same bases
Keep the base and subtract the exponents
Examples
