$\frac{3}{\sqrt[3]{x^{2}}}$

Step 1

Write $\frac{3}{\sqrt[3]{x^{2}}}$ as a function.

$f (x) = \frac{3}{\sqrt[3]{x^{2}}}$

Step 2

The function $F (x)$ can be found by finding the indefinite integral of the derivative $f (x)$ .

$F (x) = \int f (x) d x$

Step 3

Set up the integral to solve.

$F (x) = \int \frac{3}{\sqrt[3]{x^{2}}} d x$

Step 4

Since $3$ is constant with respect to $x$ , move $3$ out of the integral.

$3 \int \frac{1}{\sqrt[3]{x^{2}}} d x$

Step 5

Apply basic rules of exponents.

Step 5.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{x^{2}}$ as $x^{\frac{2}{3}}$ .

$3 \int \frac{1}{x^{\frac{2}{3}}} d x$

Step 5.2

Move $x^{\frac{2}{3}}$ out of the denominator by raising it to the $- 1$ power.

$3 \int {(x^{\frac{2}{3}})}^{- 1} d x$

Step 5.3

Multiply the exponents in ${(x^{\frac{2}{3}})}^{- 1}$ .

Step 5.3.2.1

Combine $\frac{2}{3}$ and $- 1$ .

$3 \int x^{\frac{2 \cdot - 1}{3}} d x$

Step 5.3.2.2

Multiply $2$ by $- 1$ .

$3 \int x^{\frac{- 2}{3}} d x$

Step 5.3.3

Move the negative in front of the fraction.

$3 \int x^{- \frac{2}{3}} d x$

Step 6

By the Power Rule, the integral of $x^{- \frac{2}{3}}$ with respect to $x$ is $3 x^{\frac{1}{3}}$ .

$3 (3 x^{\frac{1}{3}} + C)$
