integral of k/(x^3)

Solution

\int \frac{k}{x ^{3}} d x

Solution

- \frac{k}{2 x ^{2}} + C

Solution steps

\int \frac{k}{x ^{3}} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= k \cdot \int \frac{1}{x ^{3}} d x

Apply the Power Rule

: - \frac{1}{2 x ^{2}}

= k (- \frac{1}{2 x ^{2}})

Simplify

k (- \frac{1}{2 x ^{2}}) : - \frac{k}{2 x ^{2}}

= - \frac{k}{2 x ^{2}}

Add a constant to the solution

= - \frac{k}{2 x ^{2}} + C
