The degree of eld extensions is multiplicative, that is, if LjK0and K0jKare nite extensions, then [L: K] = [L: K0] [K0: K]. Since also the number of embeddings is multiplicative in a similar way, one deduces by induction on Nettet7. aug. 2024 · Then the elements of these fields are just polynomials in these numbers, but from here i was not able to conclude.

That is, L is modular over L n k'/P. Also, (L rl k'/P) nLpn equals Lpn f k1/P, and by 1.1 this is linearly disjoint from k. Thus by 1.4 (a) we con-clude that kLpn and L fl k'/P are linearly disjoint over k[Lpn r kl/p], and in particular have that field as their intersection. 2. saint jerry the goatfukerNettetLinearly Disjoint.
