设集合M={1,2,3,4,5},集合N={2,4,6},集合T={4,5,6},则(M∩T)∪N是( )A. {2,4,5,6}B. {4,5,6}C. {1,2,3,4,5,6}D. {2,4,6}
问题描述:
设集合M={1,2,3,4,5},集合N={2,4,6},集合T={4,5,6},则(M∩T)∪N是( )
A. {2,4,5,6}
B. {4,5,6}
C. {1,2,3,4,5,6}
D. {2,4,6}
答
知识点:此题主要考查交集和并集的定义,注意有括号先算括号里面的,此题是一道基础题;
∵集合M={1,2,3,4,5},集合T={4,5,6},
M∩T={4,5},∵集合N={2,4,6},
∴(M∩T)∪N={2,4,5,6},
故选A;
答案解析:已知集合M={1,2,3,4,5},集合N={2,4,6},集合T={4,5,6},根据交集的定义求出M∩T,再根据并集的定义求出(M∩T)∪N;
考试点:交、并、补集的混合运算.
