Find all solutions of the Diophantine Equation 3x^2 + 2y^4 = z^4
I have just found x=0, y=o, and z=0. I think that I need to use some congruence theory here, but I'm not really sure. I was suggested that if I tried the assumption that either y or z are divisible by three I would get a contradiction, but I have worked on it, and I can't really see it.
