Finding a general solution to an exact differential equation.
Hellooo.

$dy/dx = 5^xln5+1/(x^2+1)$

I know I need to move the dx to the other side, but after that, Idk what direction to go in.
I'm thinking u and du?

Have you learned how to differentiate functions of the form $a^x$ yet? Try differentiating $a^x=e^{x\ln a}$ and see what you get.

The derivative of $\arctan x$ is also $\frac{1}{1+x^2}$.
