(1)A∪B ={2,3,4,5,6,8,9,11}(2)CUA={1,3,5,7,9,10,11,13} (3)A∩B ={4,6,8} ,CU(A∩B)={1,2,3,5,7,9,10,11,13}(4)CUB ={1,2,7,10,13},A∪(CUB)={1,2,4,6,7,8,10,13}解析本小题根据交集、并集、补集的定义求解即可.
(1)A∪B ={2,3,4,5,6,8,9,11(2)CUA={1,3,5,7,9,10,11,13} (3)A∩B ={4,6,8} ,CU(A∩B)={1,2,3,5,7,9,10,11,13}(4)CUB ={1,2,7,10,13},A∪(CUB)={1,2,4,6,7,8,10,13}
(1)A∪B ={2,3,4,5,6,8,9,11(2)CUA={1,3,5,7,9,10,11,13} (3)A∩B ={4,6,8} ,CU(A∩B)={1,2,3,5,7,9,10,11,13}(4)CUB ={1,2,7,10,13},A∪(CUB)={1,2,4,6,7,8,10,13}
