integral of 2x(x^2+3)^4

\int 2 x (x^{2} + 3)^{4} d x

\frac{1}{5} (x^{2} + 3)^{5} + C

Solution steps

\int 2 x (x^{2} + 3)^{4} d x

Take the constant out:

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

= 2 \cdot \int x (x^{2} + 3)^{4} d x

Apply u-substitution

: \int \frac{u ^{4}}{2} d u

= 2 \cdot \int \frac{u ^{4}}{2} d u

Take the constant out:

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

= 2 \cdot \frac{1}{2} \cdot \int u^{4} d u

Apply the Power Rule

: \frac{u ^{5}}{5}

= 2 \cdot \frac{1}{2} \cdot \frac{u ^{5}}{5}

Substitute back

u = x^{2} + 3

= 2 \cdot \frac{1}{2} \cdot \frac{( x ^{2} + 3 ) ^{5}}{5}

Simplify

2 \cdot \frac{1}{2} \cdot \frac{( x ^{2} + 3 ) ^{5}}{5} : \frac{1}{5} (x^{2} + 3)^{5}

= \frac{1}{5} (x^{2} + 3)^{5}

Add a constant to the solution

= \frac{1}{5} (x^{2} + 3)^{5} + C

\frac{\partial}{\partial y} (y sin (x y))

\frac{d}{d x} ((ln (x))^{5})

\int 8 x e^{8 x} d x

ln^{3} (x)

\frac{d y}{d x} = \frac{( 1 - 3 y ) ^{2}}{x}, y (1) = 1
