But i mean that in the most un-interested way possible. I leave that job to waf and other white people.

justin, here's a brain teaser for you:
lim n->oo (a^n + b^n)^(1/n)
given 0 less or equall to a less or equall to b
as n--->oo, (a^n+b^n)^(1/n)--->b because a gets less and less significant when compared to b as the powers get greater because a is smaller.

now something funner:

lim n->oo n^(1/n)

now something funner:

lim n->oo n^(1/n)
A = lim(n->inf) n^(1/n)

ln A = lim(n->inf) (1/n)ln(n)

limit to 0, by l'hopitals rule

:. A = 1

i think...

I could go through an inductive proof that n^(1/n)>(n+1)^(1/(n+1)) but to be honest I'm too tired so I'll just take that as given. It approaches 1.
