WebHilbert's Theorem 90 Let L/K be a finite Galois extension with Galois group G, and let ZC7 be the group ring. If a £ L* and g £ G, we write ag instead of g(a). Since a" is the rath power of a as usual, in this way L* becomes a right ZG-module in the obvious way. For example, if r = 3g + 5 G ZC7, then of = (a$)g(as).
