A distribution function such as the Maxwell-Boltzmann distribution can be described in terms of moments, where the nth moment of a distribution P(x) is written

(he moment does not have to be evaluated relative to the mean value 8x9, but it is the convention.) Find the third moment of the Maxwell-Boltzmann distribution.
