Question

Use the multiplication rule to simplify:
67.6²

Answer 1

I'm guessing that you want to simplify
`67.6^2`

The two above the 67.2 is a square or a power.

Usually when you take something to a power, you mutiply the number of time by the power:

Examples:
`78^2` would be 78*78

`23^5` would be 23*23*23*23*23

Questions?

67.6² would simply be 67.6*67.6.

So therefore it is 4569.76

Answer 2

4569.76 you cannot simplify that
