Sophie Germain. Sorry that I didnt post a proof but I guess its easy to proceed once you write it as \(a^{4}+4b^{4}\) By the way, I am curious- Where did you get this from @Victor Loh ? This same problem appeared in TNMO-2009!! Whoa!!! I am supercurious!!!

How come a TNMO problem is a Raffles'Problem? Do they teach you such advanced math at 12? I'm amazed.
