$\int x e^{\sqrt{x}} d x$

Step 1

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

$\frac{d}{d x} [\int x e^{x^{\frac{1}{2}}} d x]$

Step 2

$\int x e^{x^{\frac{1}{2}}} d x$ is an antiderivative of $x e^{x^{\frac{1}{2}}}$ , so by definition $\frac{d}{d x} [\int x e^{x^{\frac{1}{2}}} d x]$ is $x e^{x^{\frac{1}{2}}}$ .

$x e^{x^{\frac{1}{2}}}$
