Question

Fie A-[-12,12] şi B={-11,13}. Determinaţi AUB, AB, A\B, B\A,C,A,C,B, C (AUB).​

Answer 1

Răspuns:

Explicație pas cu pas:

A={ -12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0 ,1,2,3,4,5,6,7,8,9,10,11,12 }

B={ -11,13 }

A∪B= { -12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1 ,0,1,2,3,4,5,6,7,8,9,10,11,12,13 }

A∩B= {-11 }

A/B= { -12,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10,11,12 }

B/A ={ 13}

B⊂A={ -11}

A⊂B={ ∅}
