integral of (e^{5x}+5e^x+7)/(e^x)

\int \frac{e ^{5 x} + 5 e ^{x} + 7}{e ^{x}} d x

- \frac{e ^{5 x} + 5 e ^{x} + 7}{e ^{x}} + 5 (\frac{1}{4} e^{4 x} + x) + C

Solution steps

\int \frac{e ^{5 x} + 5 e ^{x} + 7}{e ^{x}} d x

Apply Integration By Parts

= - \frac{e ^{5 x} + 5 e ^{x} + 7}{e ^{x}} - \int - 5 (e^{4 x} + 1) d x

\int - 5 (e^{4 x} + 1) d x = - 5 (\frac{1}{4} e^{4 x} + x)

= - \frac{e ^{5 x} + 5 e ^{x} + 7}{e ^{x}} - (- 5 (\frac{1}{4} e^{4 x} + x))

Simplify

= - \frac{e ^{5 x} + 5 e ^{x} + 7}{e ^{x}} + 5 (\frac{1}{4} e^{4 x} + x)

Add a constant to the solution

= - \frac{e ^{5 x} + 5 e ^{x} + 7}{e ^{x}} + 5 (\frac{1}{4} e^{4 x} + x) + C
