integral of 1/((4-2x)^{7/2)}

\int \frac{1}{( 4 - 2 x ) ^{\frac{7}{2}}} d x

\frac{1}{5 ( 4 - 2 x ) ^{\frac{5}{2}}} + C

Solution steps

\int \frac{1}{( 4 - 2 x ) ^{\frac{7}{2}}} d x

Apply u-substitution

= \int - \frac{1}{2 u ^{\frac{7}{2}}} d u

Take the constant out:

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

= - \frac{1}{2} \cdot \int \frac{1}{u ^{\frac{7}{2}}} d u

Apply the Power Rule

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

Substitute back

u = 4 - 2 x

= - \frac{1}{2} (- \frac{2}{5 ( 4 - 2 x ) ^{\frac{5}{2}}})

Simplify

- \frac{1}{2} (- \frac{2}{5 ( 4 - 2 x ) ^{\frac{5}{2}}}) : \frac{1}{5 ( 4 - 2 x ) ^{\frac{5}{2}}}

= \frac{1}{5 ( 4 - 2 x ) ^{\frac{5}{2}}}

Add a constant to the solution

= \frac{1}{5 ( 4 - 2 x ) ^{\frac{5}{2}}} + C
