Ever learnt how to use search engines?
I know how to google or search something. If fermat's theorem is the only one I am asking for then your link may be sufficient. But in the link I cannot find any relation of 3k+1 and 3k+2 with fermat theorem.
First try to be polite with others. If you know something even its something minute to think, just explain them. because they may be beginners like me or they do not understand something they have studied in their search and have asked in the forum so that someone can explain it clearly.
P.S.: BTW, in case you didn't know, it was already solved... :wink:
what does it mean "it was already solved". what is solved
