I asked this question yesterday, and it was put on hold because "it is not clear what I am asking". Is it really unclear? How clearer can I be in asking my question?
Here is the entire body of your Question:
I saw this question for example, but I don't understand the proof there. Can you please explain how to do that?
I tried to prove it and I have some thoughts, though I don't think they are worth mentioning.
Yes, a reasonable Reader might find it unclear what you are asking. From the brief contents of the Question's body, it seems you have difficulty with something that was proved in various places, and in particular in the one linked previous Question.
But what difficulty are you having? Are there definitions that are unfamiliar to you? Is there a step that seems to be a leap/unsupported? Is the approach taken a dubious one, either intuitively or because it seems similar to faulty proofs you've seen?
While your thoughts and attempts may seem "not worth mentioning" to you, you have the advantage of your Readers. You are already familiar with those thoughts and attempts, and Readers will have to guess at what about previous proofs seem inadequate or misguided or incomprehensible in your view.
Fill in those blanks (self-contained problem statement in the body, summary of your attempts or other context to let Readers see where you may need help), and the Question will be more valuable as content for Math.SE.
