$y = \frac{975}{\sqrt[3]{x}}$

Step 1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{x}$ as $x^{\frac{1}{3}}$ .

$\frac{d}{d x} [\frac{975}{x^{\frac{1}{3}}}]$

Step 2

Since $975$ is constant with respect to $x$ , the derivative of $\frac{975}{x^{\frac{1}{3}}}$ with respect to $x$ is $975 \frac{d}{d x} [\frac{1}{x^{\frac{1}{3}}}]$ .

$975 \frac{d}{d x} [\frac{1}{x^{\frac{1}{3}}}]$

Step 3.2.1

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

$975 \frac{d}{d x} [x^{\frac{1}{3} \cdot - 1}]$

Step 3.2.2

Combine $\frac{1}{3}$ and $- 1$ .

$975 \frac{d}{d x} [x^{\frac{- 1}{3}}]$

Step 3.2.3

Move the negative in front of the fraction.

$975 \frac{d}{d x} [x^{- \frac{1}{3}}]$

Step 4

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

$975 (- \frac{1}{3} x^{- \frac{1}{3} - 1})$

Step 5

To write $- 1$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$975 (- \frac{1}{3} x^{- \frac{1}{3} - 1 \cdot \frac{3}{3}})$

Step 6

Combine $- 1$ and $\frac{3}{3}$ .

$975 (- \frac{1}{3} x^{- \frac{1}{3} + \frac{- 1 \cdot 3}{3}})$

Step 7

Combine the numerators over the common denominator.

Step 9

Move the negative in front of the fraction.

$975 (- \frac{1}{3} x^{- \frac{4}{3}})$

Step 10

Combine $x^{- \frac{4}{3}}$ and $\frac{1}{3}$ .

$975 (- \frac{x^{- \frac{4}{3}}}{3})$

Step 11

Multiply $- 1$ by $975$ .

$- 975 \frac{x^{- \frac{4}{3}}}{3}$

Step 12

Combine $- 975$ and $\frac{x^{- \frac{4}{3}}}{3}$ .

$\frac{- 975 x^{- \frac{4}{3}}}{3}$

Step 13

Move $x^{- \frac{4}{3}}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{- 975}{3 x^{\frac{4}{3}}}$

Step 14

Factor $3$ out of $- 975$ .
