$m = \frac{1}{n^{6}}$

Step 1

Differentiate both sides of the equation.

$\frac{d}{d n} (m) = \frac{d}{d n} (\frac{1}{n^{6}})$

Step 2

The derivative of $m$ with respect to $n$ is $m'$ .

$m'$

Step 3.1.2.1

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

$\frac{d}{d n} [n^{6 \cdot - 1}]$

Step 3.1.2.2

Multiply $6$ by $- 1$ .

$\frac{d}{d n} [n^{- 6}]$

Step 3.2

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

$- 6 n^{- 7}$

Step 3.3.2.2

Move the negative in front of the fraction.

$- \frac{6}{n^{7}}$

Step 4

Reform the equation by setting the left side equal to the right side.

$m' = - \frac{6}{n^{7}}$

Step 5

Replace $m'$ with $\frac{d m}{d n}$ .
