$\frac{1}{4 \sqrt[4]{x^{3}}}$

Step 1

Write $\frac{1}{4 \sqrt[4]{x^{3}}}$ as a function.

$f (x) = \frac{1}{4 \sqrt[4]{x^{3}}}$

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.

$F (x) = \int \frac{1}{4 \sqrt[4]{x^{3}}} d x$

Step 4

Since $\frac{1}{4}$ is constant with respect to $x$ , move $\frac{1}{4}$ out of the integral.

$\frac{1}{4} \int \frac{1}{\sqrt[4]{x^{3}}} d x$
