comment Example of a rational function such that : $(f(x))^{3} + (g(x))^{3} + (h(x))^{3}=x$
@lhf: In the page linked by Gerry you have several solutions and links as: $(m^3-3^6n^9)^3 + (-m^3+3^5mn^6+3^6n^9)^3 + (3^3m^2n^3+3^5mn^6)^3$ $= m(3^2m^2n^2 +3^4mn^5+3^6n^8)^3$.

comment The number of symmetric polynomials of n degree
I don't understand what you mean by invariant, do you mean homogenous?, all the terms have the same total degree? take this four examples with $n=3$ and $k=2$, a) $x^3+y^3$, b) $x^2y + xy^2$, c) $x^3+y^3 + x + y$ d) $x^2y + xy^2+x+y$, which are you counting as degree 3?

comment Find maximum divisors of a number in range
PARI-GP is a great program to perform number theoretic calculations. The algorithm I've used is the same I have described, but PARI-GP knows how to handle big numbers and that makes everything easier.

comment Help complete a proof of Dirichlet on biquadratic character of 2?
2 is a biquadratic residue if and only if there is an $y$ with $y^4\equiv 2\pmod{p}$ if and only if $2^{(p-1)/4} \equiv (y^4)^{(p-1)/4} \equiv 1 \pmod{p}$ the last iif can be seen for example using a primitive root mod $p$.

comment Are limits on exponents in moduli possible?
To define limits in modular equations you need a topology, I think that what you are lookimg is $p$-adic analysis. But even with a proposition like $\lim x^{f(n)/g(N)} \ne y$ in $\mathbb{Q}_p$ (if that can be properly defined) for every $p$ I'm not sure if you could derive that $x^d \ne y$ in $\mathbb{R}$

comment Fast method for Nth Squarefree number (using mathematica)
I'm sorry, I had misunderstood the question. But you can use the same formula combined with a binary search. It will take only a few applications of the formula.
