This activity is about the division of algebraic terms with powers.
Do the following division.
Remember what a9 and a3 mean and divide them. We get:
a x a x a x a x a x a x
a x a x a a x a x a
Each a from the bottom of the fraction will cancel out with an a from the top leaving a6
This process can be simplified into the rule
am ÷ an = am-n
Let's have a go at applying that rule in the questions that follow.
