integral of 4/(x^3)

Solution

\int \frac{4}{x ^{3}} d x

Solution

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

Solution steps

\int \frac{4}{x ^{3}} d x

Take the constant out:

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

= 4 \cdot \int \frac{1}{x ^{3}} d x

Apply the Power Rule

= 4 (- \frac{1}{2 x ^{2}})

Simplify

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

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

Add a constant to the solution

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