comment If $F$ is finite over $L_1$ and $L_2$, is it also finite over $L_1 \cap L_2$?
I have thought about it, but I couldn't prove it nor find a counterexample.

comment Finding inverse of polynomial in a field
@miloszmaki: Remember that the polynomials have coefficients in $\mathbb F_3$, so that $4 = 1$ and $1/2 = 2$ and $-1 = 2$. Thus the solution you propose is actually the same as mine.
