Difficulty level:   #### Worksheet Overview

This activity is about multiplying and dividing indices.

= ( a x a x a x a) x (a x a)

= a4+2 = a6

To multiply terms containing the same letter in index form, we simply add the powers.

Example 2

y7 x y3

= y7+3

= y10

To divide terms containing the same letter in index form, we need to subtract the powers.

Example

y8 ÷ y3

= y8-3

= y5
