integral of (2e^x+8x^7)

\int (2 e^{x} + 8 x^{7}) d x

2 e^{x} + x^{8} + C

Solution steps

\int 2 e^{x} + 8 x^{7} 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 2 e^{x} d x + \int 8 x^{7} d x

\int 2 e^{x} d x = 2 e^{x}

\int 8 x^{7} d x = x^{8}

= 2 e^{x} + x^{8}

Add a constant to the solution

= 2 e^{x} + x^{8} + C
