U={1,2,3,4,5,6},A={2,3,5},B={1,4}.Cu(A∪B)与(CuA)∩(CuB)
U={1,2,3,4,5,6},A={2,3,5},B={1,4}.Cu(A∪B)与(CuA)∩(CuB)
已知全集U={1,2,3,4,5,6,7,8},A={3,4,5},B={4,7,8}.求CuA,CuB,Cu∩CuB,
U={1,2,3,4,5,6},A={2,3,5},B={1,4},求Cu(AUB)与(CuA)∩(CuB)
集合U=1,2,3,4,5,6,B=1,4A=2,3,5,求Cu(AYB)与(CuA)I(CuB)
设U={1,2,3,4,5,6,7,8},A={3,4,5},B={4,7,8},求CuA,CuB,(CuA)∩(CuB
已知全集U={1,2,…,9,10},A={1,3,5},B={2,4,6,8},求CuA,CuB,A∩CuB,A∪Cu
已知U={1,2,3,4,5,6,7,8} A∩B={2})B∩ (CuA)={1,9} (CuA)∩(CuB)={4,
设全集U={1,2,3,4,5}若A∩B={2},(CuA)∩B={4},(CuA)∩(CuB)={1,5}
已知U={x是小于20的正质数},A∩CuB={3,5},B∩(CuA)={7,19},(CuA)∩(CuB)={2,1
已知U={1,2,3,4,5,6,7,8},A∩(CuB)={1,8},(CuA)∩B={2,6},(CuA)∩(CuB
为什么Cu(CuA)=A,Cu(A U B)=(CuA)∩(CuB)
1.设U=R集合A={X/X<-1}集合B={X/-2≤X<3}求CuA∪CuB CuA∩CuB
