Indices (or exponents) are used to write statements in shorthand where repeated multiplication is used.
Indices (or exponents) are used to write statements in shorthand where repeated multiplication is used.
For example, 6 × 6 × 6 × 6 × 6 × 6 × 6 can be written as 67
In the following short tutorial I try and explain this in far more detail and introduce some algebraic methods…
Summary Exercise
Multiplication Rule (1)
In this tutorial you are shown the rules for simplifying expressions involving multiplication
Summary Exercise
Multiplication Rule (2)
The next video tutorial extends the multiplication rule.
Summary Exercise
Next you are shown how to handle the rules for dividing expressions containing indices.
Summary Exercise
Next I introduce you to negative indices which is an extension of the division rule.
Summary Exercise
In the next video you are shown how to work with rational (fractional) indices.
Summary Exercise
You will need to be able to simplify terms with negative indices. Plenty of examples to try in this next video.
Next you are shown how to solve equations where the unknown is a power.
This is a summary of all the rules for indices or exponents.
