integral of (5x+9)^{10}

\int (5 x + 9)^{10} d x

\frac{1}{55} (5 x + 9)^{11} + C

Solution steps

\int (5 x + 9)^{10} d x

Apply u-substitution

= \int \frac{u ^{10}}{5} d u

Take the constant out:

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

= \frac{1}{5} \cdot \int u^{10} d u

Apply the Power Rule

= \frac{1}{5} \cdot \frac{u ^{11}}{11}

Substitute back

u = 5 x + 9

= \frac{1}{5} \cdot \frac{( 5 x + 9 ) ^{11}}{11}

Simplify

\frac{1}{5} \cdot \frac{( 5 x + 9 ) ^{11}}{11} : \frac{1}{55} (5 x + 9)^{11}

= \frac{1}{55} (5 x + 9)^{11}

Add a constant to the solution

= \frac{1}{55} (5 x + 9)^{11} + C
