设集合X={0,1,2,4,5,7},Y={1,3,6,8,9},Z={3,7,8},那么集合(X∩Y)∪Z是( )A.{0,1,2,6,8} | B.{3,7,8} | C.{1,3,7,8} | D.{1,3,6,7,8} |
|
答案
X∩Y={1},(X∩Y)∪Z={1,3,7,8}, 故选C |
举一反三
已知集合A={1,2,3,4},B={x|x=n2,n∈A},则A∩B=( )A.{1,4} | B.{2,3} | C.{9,16} | D.{1,2} |
|
已知集合A={1,3,a},B={1,a2},且A∩B={1,a},求实数a的值. |
设集合M={4,5,6,8},集合N={3,5,7,8},那么M∪N=( )A.{3,4,5,6,7,8} | B.{5,8} | C.{3,5,7,8} | D.M={4,5,6,8} |
|
已知集合A={2,3},B={2,3,5},则集合A∪B=( )A.{2} | B.{2,3} | C.{2,3,5} | D.{2,3,2,3,5} |
|
已知集合M={3,2a},N={a,b},若M∩N={2},则M∪N=______. |
