Answer
(A∩C) ' = {a,b,c,d,e,f,g,h}
Work Step by Step
U = {a,b,c,d,e,f,g,h}
A = {a,g,h}
B = {b,g,h}
C = {b,c,d,e,f}
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 empty list.
Therefore set (A∩C) ' contains {a,b,c,d,e,f,g,h}.
