Or in case A is EVEN we can put: $B= ((A/2)^2) -1$ ; $C= ((A/2)^2) +1)$ And we come back in the same identity, so also for any A EVEN exist a couple B, C as above described, that satisfy the equation. Under Fermat's conditions, for any $A\in N$ exist a couple of $B, C \in N$ as above described, that satisfy the: $A^2 = C^2 - B^2$ Note: this A,B,C triplets as described, ARE NOT 'ALL' THE POSSIBLE TRIPLETS.

I hope, I also prove: no solution also for $A,B,C \in Q$ for $n>=3$ (and that it's possible to keep a weak condition: A,B,C pair coprimes, not necessary to be 3 coprimes) Still if I've no answers on all that, I'm quite confident this "simple" poof is correct. I'm now living more in pace... free to better prove what already said on Beal... Thanks to mymathforum for the guest, space ad time !

Here all my work on Complicate Modulus Algebra, Fermat & Beal: https://www.academia.edu/29726700/The_Two_Hands_Clock The arXiv version will folow asap, I hope cleaned enough and of course without Appendix and note for beginners... November 9th, 2016, 09:15 AM #15 Banned Camp   Joined: Dec 2012 Posts: 1,028 Thanks: 24 What I don't write but will be clear to who really understand my method is that for $n>3$ if FLT equation has integers/rational solution for $C$, than any height $C^n/K$, for $K\in N$ taken on $Y=2X^n$, must be squarable in the Rationals once we keep $A, B\in N$, but this cannot be possible because each value coming from putting $Y= C^n/K$ in $Y=2X^n$ Will give back a different irrational... so this means that indipendently by the irrational Upper Limit we choose, we can square the area bellow the derivate with the Rational Sum I show... While I've shown, in general, it's not possible to square an Irrational with a Sum or a Step Sum. The only condition is the trivial one where the irrational part of the number can be taken out from the number (so from the Sum) as a factor. But in this case we cannot compare Sums with integer/rational index (A, B), with the one multiplied by such irrational... I confess I really laughing thinking on how many Professors will have to eat a brand new cap.... ;-P I'm trying to go ArXiv, but they change again the latex formatting standard... I'll never give up ! Ciao Stefano Last edited by complicatemodulus; November 9th, 2016 at 09:19 AM.

Ciao Stefano p.s. some error in the previous post, but no time to fix it now.
