Question

Why the following sets are not equal?(1) A=[5, 6,7,8]and B =[5, 7,8].​

Answer 1

A = {5 , 6 , 7 , 8}

B = {5 , 7 , 8}

set A ≠ set B because if the two sets should be equal, then all the all elements in the both sets should be equal. But here 5 , 6 , 7 , 8 £ A and 5 , 7 , 8 £ B , So the 6 is not belongs to B.

So B is a subset of A but not equal to A.
