integral of (e^x+4^x)

\int (e^{x} + 4^{x}) d x

e^{x} + \frac{2 ^{2 x - 1}}{ln ( 2 )} + C

Solution steps

\int e^{x} + 4^{x} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int e^{x} d x + \int 4^{x} d x

\int e^{x} d x = e^{x}

\int 4^{x} d x = \frac{2 ^{2 x - 1}}{ln ( 2 )}

= e^{x} + \frac{2 ^{2 x - 1}}{ln ( 2 )}

Add a constant to the solution

= e^{x} + \frac{2 ^{2 x - 1}}{ln ( 2 )} + C

\int sin (3 x) cos^{4} (3 x) d x

\int (7 x - 1) e^{2 x} d x

\int 0.04 x + 27 d x

\int x tan^{2} (x^{2}) sec^{2} (x^{2}) d x
