integral of (x^7e^x-8x^6)/(x^7)

\int \frac{x ^{7} e ^{x} - 8 x ^{6}}{x ^{7}} d x

e^{x} - 8 ln ∣ x ∣ + C

Solution steps

\int \frac{x ^{7} e ^{x} - 8 x ^{6}}{x ^{7}} d x

Expand

\frac{x ^{7} e ^{x} - 8 x ^{6}}{x ^{7}} : e^{x} - \frac{8}{x}

= \int e^{x} - \frac{8}{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 \frac{8}{x} d x

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

\int \frac{8}{x} d x = 8 ln ∣ x ∣

= e^{x} - 8 ln ∣ x ∣

Add a constant to the solution

= e^{x} - 8 ln ∣ x ∣ + C

\frac{d}{d x} (lo g_{18} (x^{2} - 5 x))

\frac{x}{e ^{x} - 1}

\frac{d}{d x} (2 ln (x^{2}))

n = 1 \sum \infty 1 0^{n} x^{n}

\int (x^{2} + 5 x + 6) cos (2 x) d x
