If [math]A[/math] is a set, [math]x\in A[/math], [math]S=\{A, B, C\}[/math] for some [math]B, C[/math] then is it true that [math]x\in A[/math]?.

That's one of the millennium problems.

Watching twin peaks right now and this scene came on right as I scrolled past this thread.

Did you miswrite the question? It's trivial that if x is in A then x is in A

>> No.9318217

>>9318184
if you mean 'is it true that x is in S', then it's only true when B = x xor C = x

Yes I miswrore it, I mean whether [math[x\in S[/math]
>>9318217
But assuming [math]B, C \neq x[/math]?

>> No.9318288

Is [math]\setzero\in\setzero[/math]?

>> No.9318342

>>9318283
then no

No but x∈∪S
