各問題について、A∩B(AとB両方に含まれる要素の集合)と A∪B(AまたはBに含まれる要素の集合)を求めます。 (1)
A = {1, 2, 4, 8, 16}, B = {2, 4, 6, 8, 10}
A∩B={2,4,8} A∪B={1,2,4,6,8,10,16} (2)
A = {1, 2, 4, 7, 11, 16}, B = {1, 3, 7, 13}
A∩B={1,7} A∪B={1,2,3,4,7,11,13,16} (3)
A = {1, 3, 6, 10, 15}, B = {1, 6, 15}
A∩B={1,6,15} A∪B={1,3,6,10,15} (4)
A = {1, 5, 13, 25}, B = {2, 4, 8, 16}
A∩B={} (空集合) A∪B={1,2,4,5,8,13,16,25} (5)
A = {1, 2, 3, 4, 5, 6, 7, 8}, B = {1, 3, 5, 7, 9, 11}
A∩B={1,3,5,7} A∪B={1,2,3,4,5,6,7,8,9,11} (6)
A = {1, 2, 3, 4, 6, 12}, B = {1, 3, 5, 15}
A∩B={1,3} A∪B={1,2,3,4,5,6,12,15}
