Question

If M is the subset of N,then (M U N) U (M n N)=​

Answer 1

Answer:

If M is the subset of N, then (M U N) U (M n N)

( M U N ) U ( M n N) = ( M U N )

Answer 2

Answer:

Given,

M is the subset of N

=》If M is the subset of N then, all the elements which are present in the set M all also present in the set N--------(1)

Here,

M union N = N [by (1)] ---------------(2)

M intersection N = M[by (1)]--------(3)

=》(M union N) union (M intersection N)

=》(N) union (M) [by (2),(3)]

=》N union M = N [by (2)]

The correct answer is set N.
