Hi guys!
I've just looked at a past year's number theory questions and one is as follows:
Let R = Z[Sqrt(-6)] & K = Q[Sqrt(-6)]. Put a = 3+2Sqrt(-6) & b = 7-6Sqrt(-6). By choosing c close to b/a, or otherwise, find c in R such that:
Normk(b-ac) < Normk(a)
I have no ideas! :-s
Any help would be most appreciated! x
