Step 2.3.2.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x}$ as $x^{\frac{1}{2}}$ .

$m + C_{1} = \frac{1}{2} \int \frac{1}{x^{\frac{1}{2}}} d x$

Step 2.3.2.2

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

$m + C_{1} = \frac{1}{2} \int {(x^{\frac{1}{2}})}^{- 1} d x$

Step 2.3.2.3

Step 2.3.2.3.1

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

$m + C_{1} = \frac{1}{2} \int x^{\frac{1}{2} \cdot - 1} d x$

Step 2.3.2.3.2

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

$m + C_{1} = \frac{1}{2} \int x^{\frac{- 1}{2}} d x$

Step 2.3.2.3.3

Move the negative in front of the fraction.

$m + C_{1} = \frac{1}{2} \int x^{- \frac{1}{2}} d x$

Step 2.3.3

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