uncool Posted June 3, 2005 Posted June 3, 2005 Someone tell me if my math is correct? [math] n^n[/math] acts like [math]n!e^n[/math], as follows: [math] \frac{(n+1)^{n+1}}{n^n} = (n+1)\frac{(n+1)^n}{n^n}[/math] [math]=(n+1)\frac{n^n+n*n^{n-1}+\frac{n(n-1)}{2}*n^{n-2}+...}{n^n}[/math] [math]=(n+1)\frac{n^n*(1+1+\frac{1}{2}+...)+n^{n-1}*(-\frac{1}{2}-\frac{3}{6}-\frac{6}{24}-\frac{10}{120}-...)}{n^n}[/math] The last terms can be dropped out because they contain a [math]\frac{1}{n}[/math] term. [math]=(n+1)\frac{n^n*e}{n^n}=e*(n+1)[/math] so after a while, the two act similarly. In this case, similarly means that if you take the ln of both and divide them, the quotient will approach one, as shown below: n [math]n!*e^n[/math] [math]n^n[/math] Ratio 1 2.718281828 1 2.718281828
