B = { 3 , 6 , 9 , 12 , 15 , 18 , 21 , 24 , 27 , 30 , . . . } We need to check where do the elements 27 , 45 , 63 ∈ to. It is clear that these elements belong to the set B . Therefore 27 , 45 , 63 ∈ B .

If A = 2 , 4 , 6 , 8 , . . . B = 3 , 6 , 9 , 12 , . . . , then fill the blank with the symbols ∈ or ∉ . 36 , 48 , 72 ∈ _ _ _ _ _

Given: Set A = 2 , 4 , 6 , 8 , . . . . . and B = 3 , 6 , 9 , 12 , . . . . The given set in Roster form is A = 2 , 4 , 6 , 8 , 10 , 12 , 14 , 16 , 18 , 20 , . . . . . B = { 3 , 6 , 9 , 12 , 15 , 18 , 21 , 24 , 27 , 30 , . . . } We need to check where do the elements 36 , 48 , 72 ∈ to. It is clear that these elements belong to the set A and B . Therefore 36 , 48 , 72 ∈ A and B .

If A = 2 , 4 , 6 , 8 , . . . B = 3 , 6 , 9 , 12 , . . . , then fill the blank with the symbols ∈ or ∉ . _ , _ , _ ∉ A and B
