Use index notation with numbers to establish the index laws with positive integral indices and the zero index (ACMNA182)
LO: To investigate index notation and use index laws to solve problems involving indices
Know:
- What indices are
- What index notation is
- The index laws
- What is a numerical expression
Understand:
- That index laws can be used to simplify numerical expressions.
Do:
- I can apply index laws to numerical expressions with integer indices.

Index Laws
Numbers that have the same base number but different indices when multiplied, you just add the indices.
Numbers that have the same base number but different indices when divided, you just subtract the indices.
Zero Index Law
