Definition:In the complex numbers, let J denote the set, {x+y√3i :x and y are in Z}. J is an integral domain containing Z. If a is in J, then N(a) is a non-negative member of Z. If a and b are in J and a|b in J, then N(a)|N(b) in Z. The units of J are 1, -1 Question:If a and b are in J and ab = 2, then prove one of a and b is a unit. Thus,...
