Homework Statement
Prove that the sequence [tex](x_n) = ((a^n+b^n)^{1/n})[/tex] converges to [tex]b[/tex], for 0 < a < b.
The Attempt at a Solution
I haven't dealt with any sequences with [tex]n[/tex]'s in the exponent, but I assume I'll have to use logarithms at some point to get at them? Can someone start me off in the right direction?
