integral of 7x^{-3}

Solution

\int 7 x^{- 3} d x

Solution

- \frac{7}{2 x ^{2}} + C

Solution steps

\int 7 x^{- 3} d x

Take the constant out:

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

= 7 \cdot \int x^{- 3} d x

Apply the Power Rule

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

= 7 (- \frac{1}{2 x ^{2}})

Simplify

7 (- \frac{1}{2 x ^{2}}) : - \frac{7}{2 x ^{2}}

= - \frac{7}{2 x ^{2}}

Add a constant to the solution

= - \frac{7}{2 x ^{2}} + C
