integral of (3*x+5)^{11}

\int (3 \cdot x + 5)^{11} d x

\frac{1}{36} (3 x + 5)^{12} + C

Solution steps

\int (3 x + 5)^{11} d x

Apply u-substitution

: \int \frac{u ^{11}}{3} d u

= \int \frac{u ^{11}}{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^{11} d u

Apply the Power Rule

: \frac{u ^{12}}{12}

= \frac{1}{3} \cdot \frac{u ^{12}}{12}

Substitute back

u = 3 x + 5

= \frac{1}{3} \cdot \frac{( 3 x + 5 ) ^{12}}{12}

Simplify

\frac{1}{3} \cdot \frac{( 3 x + 5 ) ^{12}}{12} : \frac{1}{36} (3 x + 5)^{12}

= \frac{1}{36} (3 x + 5)^{12}

Add a constant to the solution

= \frac{1}{36} (3 x + 5)^{12} + C

\int (13 - x) d x

\frac{x ^{2}}{2 + x}

f (x) = 2 x^{3} - 4

\frac{d}{d x} (2 x + \frac{6}{x})

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