Prove in any axiomatic set theory that:2ε{a,2,b} , where a,b are letters
Country Boy said:What is the definition of "{a, 2, b}" in "axiomatic set theory"? What is the definition of "ε"?
Or even better, starting from where you left off: [math]\{ a, 2 \} \cup \{ b \} = \left ( \{ a \} \cup \{ 2 \} \right ) \cup \{ b \}[/math]solakis said:{a,2,b}={a,2}U{b}
