You did read the discussion, didn't you? I asked explicitly to avoid mere proclamations and provide rationale behind accepted definitions. "An x is called square root of y, in case y >= 0 and x*x = y. (Consequently square root of negative number doesn't exist by definition.)" If you wish, I know rationale behind the definition above, but it has nothing to do with correctness of factorization or its uniqueness as Joerg tried to "prove". -- HE CE3OH...
