integral of (3x+5)^6

\int (3 x + 5)^{6} d x

\frac{1}{21} (3 x + 5)^{7} + C

Solution steps

\int (3 x + 5)^{6} d x

Apply u-substitution

: \int \frac{u ^{6}}{3} d u

= \int \frac{u ^{6}}{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^{6} d u

Apply the Power Rule

: \frac{u ^{7}}{7}

= \frac{1}{3} \cdot \frac{u ^{7}}{7}

Substitute back

u = 3 x + 5

= \frac{1}{3} \cdot \frac{( 3 x + 5 ) ^{7}}{7}

Simplify

\frac{1}{3} \cdot \frac{( 3 x + 5 ) ^{7}}{7} : \frac{1}{21} (3 x + 5)^{7}

= \frac{1}{21} (3 x + 5)^{7}

Add a constant to the solution

= \frac{1}{21} (3 x + 5)^{7} + C

\frac{\partial}{\partial x} (5 cos (5 x))

x \to 0 + lim (\frac{x}{∣ x ∣})

\int_{0}^{1} 2 π (x + 10) (x^{2}) d x

\frac{\partial}{\partial x} (x y e^{x yz})

\int t + 1 d t
