a) AUB
b) AUC
c) DUB
d) CUD
e) (AUB)UC
f) (BUC)UD
g) (AUD)UB
h) (CUA)U(DUB)

AUB ={1,2,3,5.}
A ) AUB = {1,2,3,5}
B) AUC= {1,2,5,6,7,8}
C) DUB= {1,3,7,8,9}
D) CUD = {5,6,7,8,9}
E) (AUB)UC = {1,2,3,5,6,7,8}
F) (BUC)UD ={1,3,5,6,7,8,9}
G) (AUD)UB = { 1,2,3,5,7,8,9}
H) (CUA)U(DUB)
CUA= { 1,2,5,6,7,8} DUB= {1,3,7,8,9}
