Students learn how to use the multiplication and division rules to simplify numbers written in index form.

As learning progresses they discover the power rule and power of zero.

**Differentiated Learning Objectives**

- All students should be able to simplify an expression using the multiplication rule.
- Most students should be able to use the multiplication and division rule to simplify expressions in index form.
- Some students should be able to derive the multiplication, division and power formulae using the rules of indices.
