May 12, 2021 at 9:42 | comment | added | Zhi-Wei Sun | Now I guess that the equation $(x^k+1)(y^m+1)=z^n+1$ with $x,y,z\in\{1,2,3,\ldots\}$, $k,m,n\in\{3,4,5,\ldots\}$ and $k\ge m$ has a unique solution: $(3^5+1)(12^3+1)=75^3+1$. | |
May 12, 2021 at 7:13 | comment | added | Zhi-Wei Sun | I find that $(3^5+1)(12^3+1)=75^3+1$, | |
May 12, 2021 at 7:02 | comment | added | Zhi-Wei Sun | I also conjecture that for each $n=3,4,5,\ldots$ the equation $(x^n+1)(y^n+1)=z^n+1$ has no positive integer solution. | |
