Question

Se dau multimile A={2,4,6,8} si B={1,3,7,9}.Aflati multi mile C={asupra b supraunitare {a apartine A, b apar tine B} si D={a supta b subunitare a apartine }, b apartine B1}

Answer 1

A = {2, 4, 6, 8}
B = {1, 3, 7, 9}
C = {2/1, 4/1, 4/3, 6/1, 6/3, 8/1, 8/3, 8/7}   supraunitare
D = {2/3, 2/7, 2/9, 4/7, 4/9, 6/7, 6/9, 8/9}   subunitare
