Write a value

Question:

Write a value of $\int\left(e^{x \log _{4} a}+e^{a \log _{4} x}\right) d x$

Solution:

We know that by using property of logarithm

$e^{x \log _{e} a}=e^{\log _{e} a^{x}}=a^{x}$ and $e^{a \log _{e} x}=e^{\log _{e} x^{a}}=x^{a}$

$y=\int a^{x}+x^{a} d x$

$y=\int a^{x} d x+\int x^{a} d x$

Use formula $\int a^{x} d x=\frac{a^{x}}{\log a}$ and $\int x^{a} d x=\frac{x^{a+1}}{a+1}$

$y=\frac{a^{x}}{\log a}+\frac{x^{a+1}}{a+1}+c$
