If x belongs to A and A belongs to B, then x Belongs to B? Determine whether true or false and explain.
answer is:-
False, Consider A = {{1},2}
clearly, 1belongs to A and A belongs to B but 1 doen't belong to B
So, x belong to A and A belongs to B need not imply that x belongs to B.
SIr Please explain and give suitable example to make me understand.
Let A={1} and B={{1},2}
1 belongs to A and A belongs to B
but 1 does not belong to B
Hence, If x belongs to A and A belongs to B, then x Belongs to B is false.
1 belongs to A and A belongs to B
but 1 does not belong to B
Hence, If x belongs to A and A belongs to B, then x Belongs to B is false.
