 16h accepted Number of solutions to $x^2\equiv b \mod p^n$ 16h comment Number of solutions to $x^2\equiv b \mod p^n$ That is exactly what I was looking for. Thank you! 18h asked Number of solutions to $x^2\equiv b \mod p^n$ 2d accepted Proving that $|P\{X=m\}-P\{Y=m\}| \leq P\{X\neq Y\}$ 2d asked Proving that $|P\{X=m\}-P\{Y=m\}| \leq P\{X\neq Y\}$ Apr 6 comment Is $\mathbb{R}\times\{0,1\}$ a manifold? Yep, literally just realized that. But thank you very much :) Apr 6 accepted Is $\mathbb{R}\times\{0,1\}$ a manifold? Apr 6 revised Finding the maximum of $f(x,y,z)=x^ay^bz^c$ where $x,y,z\in [0,\infty)$ and $x^k+y^k+z^k=1$ edited body Apr 6 comment Finding the maximum of $f(x,y,z)=x^ay^bz^c$ where $x,y,z\in [0,\infty)$ and $x^k+y^k+z^k=1$ @LeGrandDODOM yeah, that is correct, it follows from the fact that the function must attain a maximum and this is the only point fitting that. Just poorly worded by me as English is not my native tongue. Will fix. Apr 6 comment Is $\mathbb{R}\times\{0,1\}$ a manifold? @ZevChonoles well this does make sense. Can you please explain the errors of my construction then?

Does that mean my solution to the problem is correct?

Apr 2 comment Finding the maximum of $f(x,y,z)=x^ay^bz^c$ where $x,y,z\in [0,\infty)$ and $x^k+y^k+z^k=1$ @Bubububu any insight on how you got to this conclusion? I'm unable to extrapolate even that unfortunately..
