integral of (2x^3-4sqrt(x))/(sqrt(x^5))

Lösung

\int \frac{2 x ^{3} - 4 x}{x ^{5}} d x

Lösung

\frac{4}{3} x^{\frac{3}{2}} + \frac{4}{x} + C

Schritte zur Lösung

\int \frac{2 x ^{3} - 4 x}{x ^{5}} d x

Multipliziere aus

\frac{2 x ^{3} - 4 x}{x ^{5}} : \frac{2 x ^{\frac{5}{2}}}{x ^{4}} - \frac{4}{x ^{4}}

= \int \frac{2 x ^{\frac{5}{2}}}{x ^{4}} - \frac{4}{x ^{4}} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{2 x ^{\frac{5}{2}}}{x ^{4}} d x - \int \frac{4}{x ^{4}} d x

\int \frac{2 x ^{\frac{5}{2}}}{x ^{4}} d x = \frac{4}{3} x^{\frac{3}{2}}

\int \frac{4}{x ^{4}} d x = - \frac{4}{x}

= \frac{4}{3} x^{\frac{3}{2}} - (- \frac{4}{x})

Vereinfache

= \frac{4}{3} x^{\frac{3}{2}} + \frac{4}{x}
