# What to do about repeatedly changing question?

This post is motivated by this question. OP first stated the question as:

" Does Fermat's Last Theorem or Euler's proof for the case n = 3 imply that $x*a^3+y*b^3 = c^3$ has no solutions in integers for $a,b,c$ positive integers and integers $x$ and $y$? Thank you.."

"I should add the condition that a,b,c,x,y cannot be 1."

After the proper changings on answers, he further changed the hypotheses:

"and the gcd(a,b) = 1."

How to proceed on this behaviour?

• @Did Sorry... what means PSQ? – Aloizio Macedo Oct 5 '15 at 19:40
• Sorry, my fault: PSQ = Problem Statement Question, i.e. a question that merely states a problem without showing effort in the form of personal thought or research or whatever. – Did Oct 5 '15 at 19:42
• @Did That would go under the "This question is missing context or other details" criteria? – Aloizio Macedo Oct 5 '15 at 19:44
• This is the idea, yes. – Did Oct 5 '15 at 19:46
