Hello,

An idea:

Par exemple , if $\displaystyle z^n=x^n+y^n$ with $\displaystyle z>y>x>0$, that it is very easy to prove that there are the relations $\displaystyle z^{n-k}<x^{n-k}+y^{n-k}$ where $\displaystyle k\in \mathbb N$* with $\displaystyle 1\leq k\leq n-1$ and so $\displaystyle x,y,z$ are the sides of a triangle having all angles smaller than a right angle.

All the best,

Integrator

The only assumption is that there are rules for mathematics. Last edited by skipjack; May 23rd, 2019 at 01:44 PM.

I provided proof how that statement affects the case for n = 2. I provided an example that Maschke used. (By the way, he has been silent of late.) 3^2 + 4^2 = 5^2. BUT 3^3 + 4^3 = 4.1^3 approximately, not 5^3. So there is agreement between calculation and example. Last edited by skipjack; May 23rd, 2019 at 01:46 PM.

FLT is not generally an interest of mine. I didn't understand your latest diagram at all but others did so I must be just losing steam altogether on this subject.
