Question

How do you multiply `uv ^ { 6} w ^ { - 8} \cdot u ^ { - 1} v ^ { 0} w ^ { - 1} \cdot u ^ { 0} v ^ { 9} w ^ { - 1}`?

Answer 1

`uv^6w^-8 * u^-1v^0w^-1 * u^0v^9w^-1=v^15w^-10`

Explanation:

Let's take it one variable at a time:

`u^1 * u^-1 * u^0 = u^0 = 1`

`v^6 * v^0 * v^9 = v^15`

`w^-8 * w^-1 * w^-1 = w^-10`

So there you go:
`uv^6w^-8 * u^-1v^0w^-1 * u^0v^9w^-1=v^15w^-10`
