题目
题型:单选题难度:一般来源:泸州一模
A.φ | B.{2,4,7,8} | C.{1,3,5,6} | D.{2,4,6,8} |
答案
∴CU(S∪T)={2,4,7,8}.
故选B.
核心考点
试题【设全集U={1,2,3,4,5,6,7,8},集合S={1,3,5},T={3,6},则∁U(S∪T)等于( )A.φB.{2,4,7,8}C.{1,3,5,】;主要考察你对集合运算等知识点的理解。[详细]
举一反三
A.{0,1} | B.{1} | C.{0,1,2} | D.ϕ |
题型:2x+1|>3},则M∩N=( )
A.(-3,-2]∪[1,2] | B.[-3,-2)∪(1,2] | C.(-3,-2)∪(1,+∞) | D.(-∞,-3)∪(1,2] |
A.{-1,-2,-3} | B.{0,1,2,3} | C.{2,3} | D.{0,-1,-2,-3} |
