Question
Finally, use the Generalized Power Rule to determine \(\frac{d}{dx}[x^9 - x]\), noting that \(x^9 - x\) is the difference of two terms.

\[
\frac{d}{dx}[(x^9 - x)^9] = 9(x^9 - x)^8 \cdot \frac{d}{dx}[x^9 - x]
\]

\[
= 9(x^9 - x)^8 \cdot \left( \frac{d}{dx}[x^9] - \frac{d}{dx}[x] \right)
\]

\[
= 9(x^9 - x)^8 \left( \text{[ ]} \right)
\]

Therefore, if \(f(x) = (x^9 - x)^9\), then we have the following result.

\[
f'(x) = \frac{d}{dx}[(x^9 - x)^9] = \text{[ ]}
\]
