Hey Guys,
I've never been on one of these sites before but am really stuck on an problem sheet I have been set. I'm doing fine in all my other modules but this algebra one doesn't seem to click well with me
Any help would be much appreciated.
So I have to prove that R is a principal ideal
domain where R is the ring {a + b(sqrt(-2)) | a,b are integers}
(by b(sqrt(-2)) I mean b multiplied by the square root of -2)
TY in advance
x
