A) AuB = {3,6,9}u{4,8} = {3,4,6,8,9} b) BuA = {4,8}u{3,6,9} = {3,4,6,8,9} c) CuD = {2,4,6,8}u{2,3,5,7} = {2,3,4,5,6,7,8} d) DuC = {2,3,5,7}u{2,4,6,8} = {2,3,4,5,6,7,8}
= {3,4,6,8,9}
b) BuA = {4,8}u{3,6,9}
= {3,4,6,8,9}
c) CuD = {2,4,6,8}u{2,3,5,7}
= {2,3,4,5,6,7,8}
d) DuC = {2,3,5,7}u{2,4,6,8}
= {2,3,4,5,6,7,8}
