Hi, i am really struggling with this question. There seems to be lots of different methods and it's very confusing! Any help would be greatly appreciated! (Happy)
Consider the field Fp with p elements. Determine the number of elements in the following groups:
So far I have (p^n -1)(p^n -p)...(p^n -p^(n-1)) and now I am stuck as my lectures are rather unhelpful!
Thanks in advance, Katie
