Use index notation with numbers to establish the index laws with positive integral indices and the zero index (ACMNA182)

[/fusion_text][fusion_text]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.

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
