$- \frac{1}{3} \cdot (x^{- 3} - x^{6})$

Step 1

Since $- \frac{1}{3}$ is constant with respect to $x$ , the derivative of $- \frac{1}{3} (x^{- 3} - x^{6})$ with respect to $x$ is $- \frac{1}{3} \frac{d}{d x} [x^{- 3} - x^{6}]$ .

$- \frac{1}{3} \frac{d}{d x} [x^{- 3} - x^{6}]$

Step 2

By the Sum Rule, the derivative of $x^{- 3} - x^{6}$ with respect to $x$ is $\frac{d}{d x} [x^{- 3}] + \frac{d}{d x} [- x^{6}]$ .

$- \frac{1}{3} (\frac{d}{d x} [x^{- 3}] + \frac{d}{d x} [- x^{6}])$

Step 3

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = - 3$ .

$- \frac{1}{3} (- 3 x^{- 4} + \frac{d}{d x} [- x^{6}])$

Step 4

Since $- 1$ is constant with respect to $x$ , the derivative of $- x^{6}$ with respect to $x$ is $- \frac{d}{d x} [x^{6}]$ .

$- \frac{1}{3} (- 3 x^{- 4} - \frac{d}{d x} [x^{6}])$

Step 5

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 6$ .

$- \frac{1}{3} (- 3 x^{- 4} - (6 x^{5}))$
