Step 1.2.1

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$\frac{d}{d x} [x^{13 \cdot - 1}]$

Step 1.2.2

Multiply $13$ by $- 1$ .

$\frac{d}{d x} [x^{- 13}]$

Step 2

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = - 13$ .

$- 13 x^{- 14}$
