integral of (2x+10)^{20}

\int (2 x + 10)^{20} d x

\frac{1}{42} (2 x + 10)^{21} + C

Solution steps

\int (2 x + 10)^{20} d x

Apply u-substitution

: \int \frac{u ^{20}}{2} d u

= \int \frac{u ^{20}}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int u^{20} d u

Apply the Power Rule

: \frac{u ^{21}}{21}

= \frac{1}{2} \cdot \frac{u ^{21}}{21}

Substitute back

u = 2 x + 10

= \frac{1}{2} \cdot \frac{( 2 x + 10 ) ^{21}}{21}

Simplify

\frac{1}{2} \cdot \frac{( 2 x + 10 ) ^{21}}{21} : \frac{1}{42} (2 x + 10)^{21}

= \frac{1}{42} (2 x + 10)^{21}

Add a constant to the solution

= \frac{1}{42} (2 x + 10)^{21} + C

\int sin (arctan (x)) d x

\int \frac{7}{( x - 9 ) ( x - 2 )} d x

\int (x^{2} + x)^{3} d x

\int \frac{30}{1 + 36 x ^{2}} d x
