integral of x^22^{x^3+1}

\int x^{2} 2^{x^{3} + 1} d x

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

Solution steps

\int x^{2} \cdot 2^{x^{3} + 1} d x

Apply u-substitution

: \int \frac{2 ^{u}}{3} d u

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

\int a^{x} d x = \frac{a ^{x}}{ln a}

= \frac{1}{3} \cdot \frac{2 ^{u}}{ln ( 2 )}

Substitute back

u = x^{3} + 1

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

Simplify

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

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

Add a constant to the solution

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

\int u^{- 2} d u

\int (x^{2} + 4)^{7} 2 x d x

\frac{d}{d x} (sin (π x + 1))

\frac{d}{d x} (tan (x^{3} + 3))

\int_{0}^{4} (x + 1)^{2} d x
