integral of 1/((3z+10)^7)

\int \frac{1}{( 3 z + 10 ) ^{7}} d z

- \frac{1}{18 ( 3 z + 10 ) ^{6}} + C

Solution steps

\int \frac{1}{( 3 z + 10 ) ^{7}} d z

Apply u-substitution

: \int \frac{1}{3 u ^{7}} d u

= \int \frac{1}{3 u ^{7}} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int \frac{1}{u ^{7}} d u

Apply the Power Rule

: - \frac{1}{6 u ^{6}}

= \frac{1}{3} (- \frac{1}{6 u ^{6}})

Substitute back

u = 3 z + 10

= \frac{1}{3} (- \frac{1}{6 ( 3 z + 10 ) ^{6}})

Simplify

\frac{1}{3} (- \frac{1}{6 ( 3 z + 10 ) ^{6}}) : - \frac{1}{18 ( 3 z + 10 ) ^{6}}

= - \frac{1}{18 ( 3 z + 10 ) ^{6}}

Add a constant to the solution

= - \frac{1}{18 ( 3 z + 10 ) ^{6}} + C

\int cot^{8} (x) csc^{4} (x) d x

\int sin (3 t) tan (3 t) d t

\int 6 x^{2} - 4 x + 7 d x

\int \frac{k}{2 x ^{2}} d x

\int sin^{4} (r) cos^{3} (r) d r
