# gamma function identity

Hi my brilliant friends.. This identity of gamma function is well known . actually I need help to prove it by using Stirling's approximation. The identity is $\Gamma (x) = \lim_{n\to\infty} \frac{n! n^{x-1}}{x(x-1)(x-2)......... (x+n-1)}$ How we can prove it by Stirling's approximation??? Please post an obvious proof.. thanks
