comment Are all finite fields isomorphic to $\mathbb{F}_p$?
Is there some special property of finite fields which gives a shorter or more elegant solution to the exercise than "By Lagrange's theorem"?

comment The odds of studying versus applying a mathematics?
This isn't actually the question discussed on meta. That question was arguably off-topic but best answered by mathematicians. This question appears to be best answered by the careers department of your university. Ask them what statistics they have on what their recent M.M. graduates are doing.

comment Logic problem, proposed by Euler
The key sentence of the problem statement has been mangled (in translation, perhaps) and makes no sense whatsoever. That makes it rather hard to check your conversion into equations.

comment What is the maximum of the self root $f(x) = x^{1/x}$
I don't see where you demonstrated that $x=e$ gives a maximum as opposed to a minimum or a saddle-point.
