oo / | | 3 | x | -- dx | x | E | / 0
$$\int\limits_{0}^{\infty} \frac{x^{3}}{e^{x}}\, dx$$
Integral(x^3/E^x, (x, 0, oo))
The answer (Indefinite)

/ | | 3 | x / 3 2\ -x | -- dx = C + \-6 - x - 6*x - 3*x /*e | x | E | /
$$\int \frac{x^{3}}{e^{x}}\, dx = C + \left(- x^{3} - 3 x^{2} - 6 x - 6\right) e^{- x}$$
