How did you find PF?

Via google search.

I love innovative ideas in math & science. Love to answer questions which are amusing & also love to ask questions which are amusing.

Welcome to PF; it's good to have you here.

Thanks for the Welcome. I'm not so familiar with Latex symbols so can I post my questions in homework thread?
Regards.

To post math equations, it's best to use the LaTeX engine that PF provides. There is a helpful "LaTeX Guide" link below the Edit window to get you started. Note that you put double-$ delimiters at the start and end of each stand-alone line of LaTeX, and double-# delimiters at the start and end of in-line LaTeX that does not need to be on its own line. Also, if you right-click on a LaTeX equation in a post, you get a pop-up menu to let you view the LaTeX source or view it in other formats.

LaTeX isn't supported in thread titles, so you can use simple text math in titles if you want.

Note also that PF uses a feature called "lazy LaTeX rendering" that speeds up page loads. When you first post your LaTeX in a thread, you will not see it rendered that first time. Just refresh your browser page to force it to be rendered, and then it should render whenever you come back to that page/thread in the future.

Let me know if you have more questions.

Just want to ask that, Can I post a question without showing my effort in homework forum, as I'm not fully familiar with latex but a little bit.
As in this question,
How to prove that the sum of squares of ##n## consecutive positive integers can never be a perfect power, where ##n## is any odd prime?
I have the proof for up to ##n=7##
But due to lack of full familiarity with Latex I'm unable to show my effort.
So, is it permissible in homework forum to post questions for people like us who are not fully but a bit familiar with the Latex symbols?
Regards.

For your first few posts, you can probably attach clear images of your hand-written work (upright, well lit, etc.), but please make it clear that you are learning LaTeX and will start to post using it in the near future. We are aware that it takes a little practice to learn LaTeX, but there is so much value in using it in posts that it is highly encouraged.

Use the "Attach files" link below the Edit window to upload PDF or JPEG images.
