$\frac{5}{36} \frac{d}{d x} [\frac{203 x^{12} - 238 x^{6} - 1}{{(x^{7} - x)}^{\frac{7}{6}}}]$

Step 3.2

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (\frac{d}{d x} [203 x^{12}] + \frac{d}{d x} [- 238 x^{6}] + \frac{d}{d x} [- 1]) - (203 x^{12} - 238 x^{6} - 1) \frac{d}{d x} [{(x^{7} - x)}^{\frac{7}{6}}]}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.3.3

Since $203$ is constant with respect to $x$ , the derivative of $203 x^{12}$ with respect to $x$ is $203 \frac{d}{d x} [x^{12}]$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (203 \frac{d}{d x} [x^{12}] + \frac{d}{d x} [- 238 x^{6}] + \frac{d}{d x} [- 1]) - (203 x^{12} - 238 x^{6} - 1) \frac{d}{d x} [{(x^{7} - x)}^{\frac{7}{6}}]}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.3.4

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 12$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (203 (12 x^{11}) + \frac{d}{d x} [- 238 x^{6}] + \frac{d}{d x} [- 1]) - (203 x^{12} - 238 x^{6} - 1) \frac{d}{d x} [{(x^{7} - x)}^{\frac{7}{6}}]}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.3.5

Step 3.3.6

Since $- 238$ is constant with respect to $x$ , the derivative of $- 238 x^{6}$ with respect to $x$ is $- 238 \frac{d}{d x} [x^{6}]$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 238 \frac{d}{d x} [x^{6}] + \frac{d}{d x} [- 1]) - (203 x^{12} - 238 x^{6} - 1) \frac{d}{d x} [{(x^{7} - x)}^{\frac{7}{6}}]}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.3.7

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

Step 3.3.8

Multiply $6$ by $- 238$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5} + \frac{d}{d x} [- 1]) - (203 x^{12} - 238 x^{6} - 1) \frac{d}{d x} [{(x^{7} - x)}^{\frac{7}{6}}]}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.3.9

Since $- 1$ is constant with respect to $x$ , the derivative of $- 1$ with respect to $x$ is $0$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5} + 0) - (203 x^{12} - 238 x^{6} - 1) \frac{d}{d x} [{(x^{7} - x)}^{\frac{7}{6}}]}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.3.10

Add $2436 x^{11} - 1428 x^{5}$ and $0$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{d}{d u} [u^{\frac{7}{6}}] \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.4.2

Differentiate using the Power Rule which states that $\frac{d}{d u} [u^{n}]$ is $n u^{n - 1}$ where $n = \frac{7}{6}$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7}{6} u^{\frac{7}{6} - 1} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.4.3

Replace all occurrences of $u$ with $x^{7} - x$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7}{6} {(x^{7} - x)}^{\frac{7}{6} - 1} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.5

To write $- 1$ as a fraction with a common denominator, multiply by $\frac{6}{6}$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7}{6} {(x^{7} - x)}^{\frac{7}{6} - 1 \cdot \frac{6}{6}} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.6

Combine $- 1$ and $\frac{6}{6}$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7}{6} {(x^{7} - x)}^{\frac{7}{6} + \frac{- 1 \cdot 6}{6}} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.7

Combine the numerators over the common denominator.

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7}{6} {(x^{7} - x)}^{\frac{7 - 1 \cdot 6}{6}} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.8

Step 3.8.1

Multiply $- 1$ by $6$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7}{6} {(x^{7} - x)}^{\frac{7 - 6}{6}} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.8.2

Subtract $6$ from $7$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7}{6} {(x^{7} - x)}^{\frac{1}{6}} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.9

Combine $\frac{7}{6}$ and ${(x^{7} - x)}^{\frac{1}{6}}$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7 {(x^{7} - x)}^{\frac{1}{6}}}{6} \frac{d}{d x} [x^{7} - x])}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.10

By the Sum Rule, the derivative of $x^{7} - x$ with respect to $x$ is $\frac{d}{d x} [x^{7}] + \frac{d}{d x} [- x]$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7 {(x^{7} - x)}^{\frac{1}{6}}}{6} (\frac{d}{d x} [x^{7}] + \frac{d}{d x} [- x]))}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.11

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 7$ .

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7 {(x^{7} - x)}^{\frac{1}{6}}}{6} (7 x^{6} + \frac{d}{d x} [- x]))}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.12

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

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7 {(x^{7} - x)}^{\frac{1}{6}}}{6} (7 x^{6} - \frac{d}{d x} [x]))}{{(x^{7} - x)}^{\frac{7}{3}}}$

Step 3.13

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

$\frac{5}{36} \cdot \frac{{(x^{7} - x)}^{\frac{7}{6}} (2436 x^{11} - 1428 x^{5}) - (203 x^{12} - 238 x^{6} - 1) (\frac{7 {(x^{7} - x)}^{\frac{1}{6}}}{6} (7 x^{6} - 1 \cdot 1))}{{(x^{7} - x)}^{\frac{7}{3}}}$

$\frac{35 (667 x^{18} - 1443 x^{12} + 993 x^{6} - 1)}{216 {(x^{7} - x)}^{- \frac{1}{6} + \frac{7 \cdot 2}{3 \cdot 2}}}$

Step 3.15.4.7.4.2

Multiply $3$ by $2$ .

$\frac{35 (667 x^{18} - 1443 x^{12} + 993 x^{6} - 1)}{216 {(x^{7} - x)}^{- \frac{1}{6} + \frac{7 \cdot 2}{6}}}$

Step 3.15.4.7.5

Combine the numerators over the common denominator.

$\frac{35 (667 x^{18} - 1443 x^{12} + 993 x^{6} - 1)}{216 {(x^{7} - x)}^{\frac{- 1 + 7 \cdot 2}{6}}}$

Step 3.15.4.7.6

Simplify the numerator.

Step 3.15.4.7.6.1

Multiply $7$ by $2$ .

$\frac{35 (667 x^{18} - 1443 x^{12} + 993 x^{6} - 1)}{216 {(x^{7} - x)}^{\frac{- 1 + 14}{6}}}$

Step 3.15.4.7.6.2

Add $- 1$ and $14$ .

$f''' (x) = \frac{35 (667 x^{18} - 1443 x^{12} + 993 x^{6} - 1)}{216 {(x^{7} - x)}^{\frac{13}{6}}}$
