integral of (3x-1)^{50}

\int (3 x - 1)^{50} d x

\frac{1}{153} (3 x - 1)^{51} + C

Solution steps

\int (3 x - 1)^{50} d x

Apply u-substitution

: \int \frac{u ^{50}}{3} d u

= \int \frac{u ^{50}}{3} 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 u^{50} d u

Apply the Power Rule

: \frac{u ^{51}}{51}

= \frac{1}{3} \cdot \frac{u ^{51}}{51}

Substitute back

u = 3 x - 1

= \frac{1}{3} \cdot \frac{( 3 x - 1 ) ^{51}}{51}

Simplify

\frac{1}{3} \cdot \frac{( 3 x - 1 ) ^{51}}{51} : \frac{1}{153} (3 x - 1)^{51}

= \frac{1}{153} (3 x - 1)^{51}

Add a constant to the solution

= \frac{1}{153} (3 x - 1)^{51} + C

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

\int \frac{y}{2 y + 1} d y

\int \frac{x + 1}{( x ^{2} + 1 ) ^{2}} d x

\int 6 x^{2} - 6 x d x

\int x (10 x^{2} + x^{\frac{1}{2}}) d x
