Question

W cubed x W (-9th Power)

Answer 1

`\frac{1}{w {}^(6) }`

Explanation:

`{w}^(3) * w {}^( - 9)`

equal

`w {}^( - 6)`

Using the product of power rule,

`{x}^(a ) * x {}^(e) = x {}^(a + e)`

Then apply negative power rule

`a {}^( - x) = \frac{1}{a {}^(x) }`

So it now becomes

`\frac{1}{w {}^(6) }`
