Question

Dados os conjuntos A ={-4,
-2, 0, 2, 4},
B=(0,1,2,3,4} e C={-2,5,7,9}, determine:

Answer 1

Resposta:

A ={-4,-2, 0, 2, 4},

B=(0,1,2,3,4} e C={-2,5,7,9}.

a)A U C= {-4,-2,0,2,4,5,7,9}

b)C n A= {-2}

c)B n C= {0,2,4}

d)C U (A n B)=

{-2,5,7,9} U {0,2,4}=

{-2,0,2,4,5,7,9}

e)B-A= {1,3}

f)A-(B U C)=

{-4,-2,0,2,4} - {-2,0,1,2,3,4,5,7,9}=

{-4}

g)B n (A-C)=

{0,1,2,3,4} n {-4,0,2,4}=

{0,2,4}

h)(A U B)-(A n B)=

{-4,-2,0,1,2,3,4} - {-4,-2}=

{0,1,2,3,4}
