integral from 1 to 2 of 15x^22^{x^3}

\int_{1}^{2} 15 x^{2} 2^{x^{3}} d x

\frac{1270}{ln ( 2 )}

Decimal

1832.22270 \dots

Solution steps

\int_{1}^{2} 15 x^{2} \cdot 2^{x^{3}} d x

Take the constant out:

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

= 15 \cdot \int_{1}^{2} x^{2} \cdot 2^{x^{3}} d x

Apply u-substitution

: \int_{1}^{8} \frac{2 ^{u}}{3} d u

= 15 \cdot \int_{1}^{8} \frac{2 ^{u}}{3} d u

Take the constant out:

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

= 15 \cdot \frac{1}{3} \cdot \int_{1}^{8} 2^{u} d u

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

= 15 \cdot \frac{1}{3} [\frac{2 ^{u}}{ln ( 2 )}]_{1}^{8}

Simplify

15 \cdot \frac{1}{3} [\frac{2 ^{u}}{ln ( 2 )}]_{1}^{8} : 5 [\frac{2 ^{u}}{ln ( 2 )}]_{1}^{8}

= 5 [\frac{2 ^{u}}{ln ( 2 )}]_{1}^{8}

Compute the boundaries:

\frac{254}{ln ( 2 )}

= 5 \cdot \frac{254}{ln ( 2 )}

Simplify

= \frac{1270}{ln ( 2 )}

(5 t + e^{t}) (3 - t)

(x^{2} y^{3} - \frac{1}{1 + 9 x ^{2}}) (\frac{d x}{d y}) + x^{3} y^{2} = 0

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

\frac{\partial}{\partial x} (x^{2} sin (3 t))

arcsin (e^{2 x})
