Rudin's proof of lim n-> inf (p^(1/n)) = 1(adsbygoogle = window.adsbygoogle || []).push({});

1+n*x_n <= (1 + x_n)^n = o

I don't see it from the binomial theorem, which is what he says that is from.

He also does things with the binomial theorem like:

(1+x_n)^n >= ((n(n-1)) / 2) *x_n^2

I'm not sure what he did to get these two inequalities.
