Question 476536
A = {3, 4, 5, 6, 7}, B = {6, 7, 8, 9}, C = {2, 4, 6, 8} List the element of this set A U (B ∩ C)


B = {6, 7, 8, 9}
C= {2,4,6,8}
Intersection ∩  means the elements which are in both the sets
(B ∩ C)={ 6,8}

Let this be named D
D= {6,8}
A = {3, 4, 5, 6, 7}

A U (B ∩ C)  U means union
all elements which are in A & D without repetition is the union
D=(B ∩ C)
A U (B ∩ C)=AUD = {3,4,5,6,7,8}
