comment Diophantine Equation $x^n+y^n=z^n$
Thanks Gerry, my answer is also along identical line. I have used the inequality $$\frac{x}{n} +y \gt z$$ This shows that when $ x <n$ then $$\frac{x}{n} < 1$$ $$\Rightarrow 1+y>\frac{x}{n}+y>z>y$$ Showing that x lies between $y$ and $y+1$ which is a fallacy considering $z$ is an integer. This brings me to the next pertinent question. What happens when $n < x$. Is there any discussion on this anywhere ?
