integral of (5x+2)^4

\int (5 x + 2)^{4} d x

\frac{1}{25} (5 x + 2)^{5} + C

Solution steps

\int (5 x + 2)^{4} d x

Apply u-substitution

= \int \frac{u ^{4}}{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^{4} d u

Apply the Power Rule

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

Substitute back

u = 5 x + 2

= \frac{1}{5} \cdot \frac{( 5 x + 2 ) ^{5}}{5}

Simplify

\frac{1}{5} \cdot \frac{( 5 x + 2 ) ^{5}}{5} : \frac{1}{25} (5 x + 2)^{5}

= \frac{1}{25} (5 x + 2)^{5}

Add a constant to the solution

= \frac{1}{25} (5 x + 2)^{5} + C
