Answer
(A∩C) ' = {1,2,4,6,7}
Work Step by Step
U = {1,2,3,4,5,6,7}
A = { 1,3,5,7}
C = {2,3,4,5,6}
The set (A∩C)' represents the elements of U which are not present in A∩C.
Since the elements of A∩C should not be present in (A∩C).
A∩C represents the common elements of A and C.
Therefore the common elements of A and C are 3,5.
So set A∩C = {3,5}
Therefore set (A∩C) ' contains {1,2,4,6,7}.
