Answer:
True
Step-by-step explanation:
Given are some sets A, B, C, D and Universal set U.
We have
[tex]A={1,3,5,7}[/tex]
When we change the order of elements of A in any manner also the set A' thus obtained will be equal to A only
Hence here A' = [tex]{7,5,3,1}[/tex]=A
This is because whenever we take any element x in A this belongs to A'
Hence [tex]A⊂A'[/tex]
Similarly any element y in A' also belongs to A
So A⊂A'
Together we have[tex]A=A'[/tex]
