is it possible to integrate something like $\displaystyle e^x.\frac{1}{2\sqrt{x}}$

because neither part will cancel so i just keep getting stuck in a perpetual loop

**Note that : $\displaystyle e^x=e^{\left( \sqrt{x} \right)^2}$**

**If you substitute $\displaystyle u=\sqrt{x}$, you will get :**

**$\displaystyle \int e^{u^2} \, du$ , which is well-known unelementary integral ..**

**Your integral can not be expressed in terms of elemenetary integrals ..**
