comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers
Thanks @user44197. I got 10 possible values for which k is integer actually by your approach. $(x_0,y_0,\mu)$ as ${(1,1,1),(1,2,1),(2,1,1),(2,3,1),(3,2,1),(1,1,2),(1,3,2),(3,1,2),(1,2,3),(2,1,3‌​)}$

You probably mean cannot exceed 6

comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers
But some solutions like (2,3,6) (3,2,6) does not say none should exceed 5

Yes that was a mistake (I can't believe I said that - looks so stupid of me)

they have to be less than 1 isn't it? How can x,y,z be greater than 1?

Are you sure those stationary points are correct?

comment Summation of Infinite Series $\sum_{n=1}^{\infty} \frac{1}{n 2^{2n+1}}$
Did you try $\sum_{n=1}^{\infty} \frac{y^n}{n} = -\ln \left(1-y\right)$

comment Generalizing an approach to proving AMGM
Instead of going so far (generalizing), why don't you try for $n=4$ and share your answer
