integral from 1 to 2 of (x^6+4x^8)/(x^5)

\int_{1}^{2} \frac{x ^{6} + 4 x ^{8}}{x ^{5}} d x

\frac{33}{2}

Decimal Notation

16.5

Solution steps

\int_{1}^{2} \frac{x ^{6} + 4 x ^{8}}{x ^{5}} d x

Expand

\frac{x ^{6} + 4 x ^{8}}{x ^{5}} : \frac{x ^{6}}{x ^{5}} + \frac{4 x ^{8}}{x ^{5}}

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}^{2} \frac{x ^{6}}{x ^{5}} d x + \int_{1}^{2} \frac{4 x ^{8}}{x ^{5}} d x

\int_{1}^{2} \frac{x ^{6}}{x ^{5}} d x = \frac{3}{2}

\int_{1}^{2} \frac{4 x ^{8}}{x ^{5}} d x = 15

= \frac{3}{2} + 15

Simplify

\frac{3}{2} + 15 : \frac{33}{2}

= \frac{33}{2}

\int x^{2} + 6 x + 2 d x

\frac{\partial}{\partial x} (x + 1 + 1)

\frac{\partial}{\partial x} (x^{2} y^{2} z)

(2 x^{2} - 1)^{- 1}

\int_{- 2}^{2} 1 + 100 x^{2} d x
