Integral Substitution Af3756
1. We are asked to evaluate the integral $$\int \frac{e^{\sqrt{x}}}{\sqrt{x}} \, dx$$.
2. To solve this, use the substitution method. Let $$t = \sqrt{x}$$, so $$x = t^2$$ and $$dx = 2t \, dt$$.
3. Substitute into the integral:
$$\int \frac{e^t}{t} \cdot 2t \, dt = \int 2 e^t \, dt$$.
4. Simplify the integral:
$$\int 2 e^t \, dt = 2 \int e^t \, dt$$.
5. The integral of $$e^t$$ is $$e^t$$, so:
$$2 e^t + C$$.
6. Substitute back $$t = \sqrt{x}$$:
$$2 e^{\sqrt{x}} + C$$.
Therefore, the solution to the integral is:
$$\boxed{2 e^{\sqrt{x}} + C}$$.
