Question

Wyznacz zbiory :

A U B =

A / B

C/A =

A= { 1,2,4,6,8,18 }

B= { 2,4,6,8,10,12,14,16,18,20 }

C= { 2,3,5,7,11,13,17,19 }

2.Wyznacz.

A U B =

A/B =

B/A =

A= ( 3,5 >

Answer 1

Zad.1

A={1;2;4;6;8;18}

B={2;4;6;8;10;12;14;16;18;20}

C={2;3;5;7;11;13;17;19}

 

A U B = {1;2;4;6;8;10;12;14;16;18;20}

A n C = {2}

A \ B = {1}

C \ A = {3;5;7;11;13;17;19}

 

Zad.2

A=(3;5>

B=<4;+∞)

 

A U B = (3;+∞)

A n B = <4;5>

A \ B = (3;4)

B \ A = (5;+∞)

Answer 2

1. A U B ={1,2,4,6,8.10,12,14,16,18,20}

={2,4,6,8,18}

A / B= {1}

C/A = {3,5,7,11,13,17,19}

 

 

2. 

 

  A U B=  

 

  =<4,5>

A/B= (3,4)

B/A =
