$f (x) = x^{0.9}$

Step 1

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 0.9$ .

$0.9 x^{- 0.1}$

Step 2

Simplify.

Step 2.1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$0.9 \frac{1}{x^{0.1}}$

Step 2.2

Combine $0.9$ and $\frac{1}{x^{0.1}}$ .

$\frac{0.9}{x^{0.1}}$
