integral of 1/((2-5x)^3)

\int \frac{1}{( 2 - 5 x ) ^{3}} d x

\frac{1}{10 ( 2 - 5 x ) ^{2}} + C

Solution steps

\int \frac{1}{( 2 - 5 x ) ^{3}} d x

Apply u-substitution

= \int - \frac{1}{5 u ^{3}} d u

Take the constant out:

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

= - \frac{1}{5} \cdot \int \frac{1}{u ^{3}} d u

Apply the Power Rule

= - \frac{1}{5} (- \frac{1}{2 u ^{2}})

Substitute back

u = 2 - 5 x

= - \frac{1}{5} (- \frac{1}{2 ( 2 - 5 x ) ^{2}})

Simplify

- \frac{1}{5} (- \frac{1}{2 ( 2 - 5 x ) ^{2}}) : \frac{1}{10 ( 2 - 5 x ) ^{2}}

= \frac{1}{10 ( 2 - 5 x ) ^{2}}

Add a constant to the solution

= \frac{1}{10 ( 2 - 5 x ) ^{2}} + C
