Also, what have you tried? If you tell us this then we will be better able to help you. And it helps us feel that we are not just doing your homework for you.

You should try not to call a question "easy" when helping someone. It does little more squash flat that person's confidence.

comment What is the meaning of “fix” in field theory?
(The implication being that because they define "fixed" to have this specific meaning, rather than assuming it, they understand the word "fixed" is ambiguous. The purpose of my answer to point out this ambiguity.)

comment What is the meaning of “fix” in field theory?
@NateEldredge Doing a Google Scholar search for "fixed setwise" automorphism brings up lots of results. My point wasn't that "fixes" doesn't have a precise meaning when talking about fields (I used the word "necessarily" as a get out clause!), but that it doesn't have a precise meaning in mathematics. I have flicked though my mini desk library, and for example Artin's Galois theory and Fraleigh's A first course in abstract algebra both define what they mean by a fixed field.
