Answer
A = {1,2,3,4) B= {3,4,2,1} Cardinal number of A is n(A) =4
Cardinal Number of B is n(B) =4
Therefore the given sets are equivalent and the individual elements in A and B are same. Therefore A and B sets are equivalent and equal.
Work Step by Step
We need to show that the two sets are equivalent and equal
As we know equivalent is the two sets having the same cardinal number
and the equal is the two sets having same cardinal number and all the individual are also same
A = {1,2,3,4} B={3,4,1,2}
The cardinal number of A = 4= the cardinal number of B.
Therefore the given sets are equivalent and equal because the elements are same of A and B.
Therefore the two sets are equivalent and equal.
