@amWhy A quite far off approximation ! If I remember right an article from the Guiness book of records , $4$ was the inaccuratest value for $\pi$ , "defined" by law around $1900$ somewhere in the USA. This one is probably on the second place.
@amWhy math.stackexchange.com/questions/4628016/… Have you seen this? the question's been closed, but the answers can be seen. In this case, the OP can take advantage and copy the answers without effort, what to do?
@SineoftheTime This is a very old problem , which cannot be solved without more and more consequent moderator-action. Unless CURED would get , say , $50$ helpers to detect and quickly delete such stuff. But we have at best about ten helpers.
@NoahSchweber Great. I thought you might have, hence the "if you haven't already". I agree that they are very bad non-answers. Likely the user is just trying to gain rep quickly, with very little clue what they are is superficial.
I know the trivial solution $(0,0,0,0)$, but i seem to struggle trying to prove that there are no other answers.
I have not been able to resolve these exercise using the condicional test (｡ŏ﹏ŏ) heelp
