Answer
Explanation:
Step1: Use substitution method
Let $u = \frac{x}{4}$, then $x = 4u$ and $dx=4du$.
Step2: Rewrite the integral
$\int e^{\frac{x}{4}}dx=\int e^{u}\cdot4du = 4\int e^{u}du$.
Step3: Integrate $e^{u}$
Since $\int e^{u}du=e^{u}+C$, then $4\int e^{u}du = 4e^{u}+C$.
Step4: Substitute back $u=\frac{x}{4}$
We get $4e^{\frac{x}{4}}+C$.
Answer:
$4e^{\frac{x}{4}}+C$
