$\frac{d x}{\sqrt{x}}$

Step 1

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

$\frac{x}{\sqrt{x}} \int d d \cdot d$

Step 2

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

$\frac{x}{\sqrt{x}} (\frac{1}{2} d^{2} + C)$
