Dividing Indices
Here the rules used are:
am ÷ an = am − n and a1 = a
Here the rules demonstrated are:
a− n = 1/an and a0 = 1
- Example 1. work out a7/a4
- Example 2. work out a4/a4
- Example 3. work out 10a6/2a3
- Example 4. work out a3/a7
- Example 5. work out 12a2/6a5
- Example 6. work out 12a/3a6
In this example the base is a
| = |  |
| = |  |
| = | a × a × a |
| = | a7 − 4 = a3 |
In this example the base is a
| = |  |
| = |  |
| = | a4 − 4 = a0 = 1 |
Remember any number divided by itself is equal to 1; this is because any number multiplied by 1 is equal to that same number.
In this example the base is a
| = |  |
| = |  |
| = | 5a × a × a |
| = | 5a6 − 3 = 5a3 |
In this example the base is a
| = |  |
| = |  |
| = |  |
| = | a3 − 7 = a−4 |
| = |  |
In this example the base is a
| = |  |
| = |  |
| = |  |
| = |  |
In this example the base is a
| = |  |
