∅ {0,2,3} {-1,1} {0,1,2,3}
{3} {4,5} {4,5,6} {0,1,2}
{0} {0,1} {0,1,3} {0,1,2,3}
={0,1,2,3}, ={0,2,4},那么A.∩(∁U.B.)等于( ) A.{1}B.{0,1} {1,3} {0,1,2,3}
{0,1,2,3} {0,2} {2,3,4} {4}
{2,3} {0,1,2} {1,2,3} {0,1}
={0,2},则集合A.的真子集共有( ) A.3个 4个 5个 6个
={0,1,2,3}, ={x|lnx>0},则A.∩B.=( ) A.{0,1,2,3}B.{1,2,3} {2,3} {3}
={0,1,2,3}, ={x|x(x-3)<0},则A.∩B.= ( ) A.{0,1,2,3}B.{0,1,2} {1,2} {1,2,3}
{3} {0,1} {0,1,2} {0,1,2,3}
={0,1,2,3}, ={x|x2=2x},则A.∩(∁U.B.)为( ) A.{1,3}B.{0,2} {0,1,3} {2}
={0,1,2,3}, ={},则= A.{4}B.{9}[ {0,1} {4,9}
{1,2,3} {2,3} {0,2} {0,2,3}
{0} {0,1} {0,1,3} {0,1,2,3}
