Question

sendo os conjuntos a= {1,0,1,2,3,4}, B = {3,4,5} e C = {-1,0,1}
determine :
a) A B=
b) (A C) - B=
c) A B C=
d) A B C=

Answer 1

Resposta:

a){1,0,2,3,4,5}

b)ac={1,0,2,3,4} - {3,4,5} = {1,0,2}

c){1,0,2,3,4,5}

d)☝️

Answer 2

Resposta:

a) A B= {-1,0,1,2,3,4,5}

b)(A C)- B= {-1,0,1,2,3,4}+ {-1,0,1}= {-1,0,1,2,3,4} -{3,4,5}= {-1,0,1,2}

c) A B C= {-1,0,1,2,3,4,5}

d) A B C= " " " " " " " "
