Question

Determinati multimile A si B stiind ca:A U B={1,2,3,4,5,6}. ,A\B={1,5}. ,B\A={2,6}

Answer 1

A = A U B \ ( B \ A ) = {1,3,4,5}
B = A U B \ ( A \ B ) = {2,3,4,6}

Answer 2

 reunire  AU B sunt elementele din cele 2 multimi 
A\B= {1,5} deci ce are A si nu are B= { 1,5+ cele de la reunire}
B\A    deci ce are A si nu are B    A={2,6  + cele de la reunire}
A={1,5,3,4,}
B={2,6,3,4}
