integral of 3x^{-6/7}

\int 3 x^{- \frac{6}{7}} d x

21 x^{\frac{1}{7}} + C

Solution steps

\int 3 x^{- \frac{6}{7}} d x

Take the constant out:

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

= 3 \cdot \int x^{- \frac{6}{7}} d x

Apply the Power Rule

: 7 x^{\frac{1}{7}}

= 3 \cdot 7 x^{\frac{1}{7}}

Simplify

= 21 x^{\frac{1}{7}}

Add a constant to the solution

= 21 x^{\frac{1}{7}} + C

\int 3 - 4 x d x

\int \frac{x}{( 4 + x ^{2} ) ^{2}} d x

\int \frac{1}{3} \cdot x^{3} cos (x^{4} + 2) d x

\int 7 cos (x) tan (x) d x

\int 7 x e^{- 4 x} d x
