comment $[F(t):F(t^n)]=n$ where $t$ is trascendental
I can't see how does that relate with $[F(t):F(t^n)]$. Do you mean that $n$ conjugates are linearly independent?

comment $[F(t):F(t^n)]=n$ where $t$ is trascendental
Why your polynomial in $t$ is not the $0$ polynomial? In that case there is no a contradiction.

comment $[F(t):F(t^n)]=n$ where $t$ is trascendental
I can't follow your idea. Why is clear for a field with n th roots of unit?

comment Infinite algebraic extension of $\mathbb{Q}$
Yes but Steinitz's theorem is unnecesary, if the extension is finite of degree $n$, by tower law you have that $k|n$ for every $k\in\mathbb{N}$ a contradiction.

Why there are no two algebraically independent elements in a simple extension?
