Step 2.3.1.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[5]{x}$ as $x^{\frac{1}{5}}$ .

$y + C_{1} = \int \frac{1}{x^{\frac{1}{5}}} d x$

Step 2.3.1.2

Move $x^{\frac{1}{5}}$ out of the denominator by raising it to the $- 1$ power.

$y + C_{1} = \int {(x^{\frac{1}{5}})}^{- 1} d x$

Step 2.3.1.3

Multiply the exponents in ${(x^{\frac{1}{5}})}^{- 1}$ .

Step 2.3.1.3.1

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

$y + C_{1} = \int x^{\frac{1}{5} \cdot - 1} d x$

Step 2.3.1.3.2

Combine $\frac{1}{5}$ and $- 1$ .

$y + C_{1} = \int x^{\frac{- 1}{5}} d x$

Step 2.3.1.3.3

Move the negative in front of the fraction.

$y + C_{1} = \int x^{- \frac{1}{5}} d x$

Step 2.3.2

By the Power Rule, the integral of $x^{- \frac{1}{5}}$ with respect to $x$ is $\frac{5}{4} x^{\frac{4}{5}}$ .

$y + C_{1} = \frac{5}{4} x^{\frac{4}{5}} + C_{2}$

Step 2.4

Group the constant of integration on the right side as $K$ .

$y = \frac{5}{4} x^{\frac{4}{5}} + K$
