设A=｛a,b,c,d,e｝,B=｛c,d,f,g｝求A集合B,A∪B

设集合A=｛a,b,c,d,e｝,集合B=｛c,d,f,g｝,求A∩B,A∪B. 设全集I={a,b,c,d,e,f,g,h},集合A={a,b,c,d,e,f},B={c,d,e},C={a,d},那 已知集合A=a,b,c,d,e B=m,n,f,g 设全集U={a,b,c,d,e,f},A={a,c,e,f},B={b,c,d,e},分别求集合Cu（A∩B）和CuA∪ a b c d e f g A B C D E F G , 设集合A=｛a,b,c｝,集合B=｛a,b,c,d,e｝,则AUB= 集合A=(a, b, c),集合B=(c ,d ,e ,f),则A∩B=? 图G=,其中V={a,b,c,d,e,f },E={(a,b),(a,c),(a,e),(b,d),(b,e),(c,e a+b+c+d+e+f+g=20 设集合A={a,b,c,d,e,f},A上的等价关系R={(a,b)(a,c)(b,a)(b,c)(c,a)(c,b)( a/b=c/d e/f=g/h ,a/b+c/d=e/f+g/h吗?
