Step 1.1

Factor $x$ out of $d x$ .

$\frac{\ln (x)}{x} \cdot (x d)$

Step 1.2

Cancel the common factor.

$\frac{\ln (x)}{x} \cdot (x d)$

Step 1.3

Rewrite the expression.

$\ln (x) \cdot d$

$\ln (x) \cdot d$

Step 2

Reorder factors in $\ln (x) d$ .

$d \ln (x)$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
