Question

Sendo a=(0,1,2,3)e B=(×/× e número par positivomenor que 10)

Answer 1

Separando os conjuntos ficam A={0,1,2,3} B={0,2,3,5} C={ infinito<10} D={5,7,9} a) (A união com B) ={0,1,2,3,5} b) (A união com D) ={ 0,1,2,3,5,7,9} c) (B união com D) ={ 0,2,3,5,7,9} d) (A união com C) ={...,-8,-6,-4,-2,0,1,2,3,4,6,8} e) (B união com C) ={...,-6,-4,-2,0,2,3,4,5,6,8} e f) (C união com D) ={...,-6,-4,-2,0,2,4,5,6,7,8,9}
