Question

determinati multimile m si p stiind ca indeplinesc simultan conditiile a) m U p = (1 2 3 4 5 6) b) M \ P = (4 6) c) M intersectat P = ( 1 3 5 )

Answer 1

M={1;3;5...?
P={1;3;5...?
 apoi vedem ca in M apar in plus 4 si 6, care nu sunt si in P
deci M= {1;3.5;4;6}
dar apoi vedem ca in reuniune e  si 2
cum 2 nu e in intersectie, nici in M , nseamna ca 2 apartine P
deci P= {1;3;5;2 }

Answer 2

MuP={1,2,3,4,5,6}
M-P={4,6}
M∩P={1,3,5}
M={1,3,5,4,6}
P={1,3,5,2}
∩ inseamna elemente comune , adica 1,3,5
M-P inseamna elementele  care le are M si nu le are P, adica 4,6
