integral from 1 to e of (x^5+1)/x

\int_{1}^{e} \frac{x ^{5} + 1}{x} d x

\frac{e ^{5} - 1}{5} + 1

Solution steps

\int_{1}^{e} \frac{x ^{5} + 1}{x} d x

Expand

\frac{x ^{5} + 1}{x} : x^{4} + \frac{1}{x}

= \int_{1}^{e} x^{4} + \frac{1}{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_{1}^{e} x^{4} d x + \int_{1}^{e} \frac{1}{x} d x

\int_{1}^{e} x^{4} d x = \frac{e ^{5} - 1}{5}

\int_{1}^{e} \frac{1}{x} d x = 1

= \frac{e ^{5} - 1}{5} + 1

\int_{0}^{8} (x^{3})^{2} d x

\int_{0}^{1} \frac{x}{1 + 3 x ^{2}} d x

\int_{0}^{\frac{6}{7}} \frac{1}{49 x ^{2} + 36} d x

\int_{- 1}^{0} \frac{3 x ^{4}}{x ^{2} + 1} d x

\int_{1}^{5} \frac{2 x}{x ^{2} - 4} d x
