@user170039 As I've explained in the comments, in a duscussion with RRL, firstly the question seems interesting to me since I see that also some expert user had some doubd or matter for a discussion on that.
Secondly, I can agree that thoughts presented by the asker can be considered poor but I think that it is a genuine discussion made within his/her range of knowledge. I really disagree with closure.
We should support user wh try to do their best within their knowledge and help them to improve their skills.
@user170039 I'd say there is some context and thoughts made by the asker after 'Is it true?' but the opinion of whether it's sufficient differs between users.

@TheSimpliFire Good point.

@gimusi If $x<0$ then can you give an example of a sequence $(x_n)_{n\in\mathbb{N}}$ converging to $x$ and $(0^{x_n})_{n\in\mathbb{N}}$ converges to $0$?
In this particular case I'm slightly tempted to side with gimusi. I've added some comments/questions below the OP and we can see if there is a reasonable answer to be written up. I do think the answers currently up are rather bad though. I think to give an answer which doesn't lend itself to misinterpretation a much more holistic view needs to be taken regarding how and why we actually define the exponential and powers in general.
I don't agree with reopening as is but the OPoster seems to be off some longish standing on MathSE so possibly they will be able to fix the question up.
@MikeMiller I wasn't arguing for it to be reopened. I even say so in the last part of that comment. I was just saying that it's worth watching. The OP is not a first time poster or something, so hopefully he will come back to edit. I agree that as is it's not reopenable.
But everyone should evaluate them by their own standards, which may be different than mine. I don't think that PSQ + some attempt that doesn't work is substantially better than just a PSQ. The extra content is just "contexty".
@RobertFrost I am not sure that I see why I should vote to reopen the question. It was not closed because it was of the wrong mathematical level, but because it is without context. Your own comment to the question confirms this: there is additional information regarding the background of the asker which would be helpful to establish context.
@RobertFrost Just because a user is at an earlier level of mathematics knowledge doesn't exempt them from providing sufficient context in the question. Again, please stop holding double standards for users.
@RobertFrost You added a comment asking for clarification. I find it rather disingenuous of you to claim that you don't know what else they could add...
For example, is this a problem from a text, or from a class? If from a class, which one, and what theorems have they seen recently? If a text, which one? For example, are they in a context of abstract algebra, or number theory, or intro to proofs, or something else?
@XanderHenderson not really because if they knew to state they had covered prime factorisation (which they obviously have) they would already have the answer
I think they know Euclid's lemma? I think they could say if they saw the problem in number theory, abstract algebra, intro to proof, somewhere else - and that context would help inform me about whether the goal of the problem was for them to apply Euclid's lemma
That's why I think the problem is missing context - because the OP didn't say where they got the problem, I don't know how to respond to it
@amWhy For the sake of transparency, all nine questions posted for deletion were obtained from page 3 of this search, and culled from the lowest voted posts, primarily closed two days ago.
