integral of 8x(4x^2+5)^6

\int 8 x (4 x^{2} + 5)^{6} d x

\frac{1}{7} (4 x^{2} + 5)^{7} + C

Solution steps

\int 8 x (4 x^{2} + 5)^{6} d x

Take the constant out:

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

= 8 \cdot \int x (4 x^{2} + 5)^{6} d x

Apply u-substitution

: \int \frac{u ^{6}}{8} d u

= 8 \cdot \int \frac{u ^{6}}{8} d u

Take the constant out:

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

= 8 \cdot \frac{1}{8} \cdot \int u^{6} d u

Apply the Power Rule

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

= 8 \cdot \frac{1}{8} \cdot \frac{u ^{7}}{7}

Substitute back

u = 4 x^{2} + 5

= 8 \cdot \frac{1}{8} \cdot \frac{( 4 x ^{2} + 5 ) ^{7}}{7}

Simplify

8 \cdot \frac{1}{8} \cdot \frac{( 4 x ^{2} + 5 ) ^{7}}{7} : \frac{1}{7} (4 x^{2} + 5)^{7}

= \frac{1}{7} (4 x^{2} + 5)^{7}

Add a constant to the solution

= \frac{1}{7} (4 x^{2} + 5)^{7} + C

\int \frac{4}{7 ^{l n (x)}} d x

x \to 0 + lim (ln (x^{x}))

\int cos (x) csc (x) d x

\frac{d}{d x} (x^{2} \cdot f (x))

\frac{d}{d x} (e^{- arcsinh (\frac{x}{2})})
