Question

Hanya soal no 1, 2, 5, 7, sama jalannya yaa..
kalau dikerjain cuma beberapa soal GPP

Answer 1

1. A = {1,2,3}
B = {2,1,5}
A U B = {1,2,3,5}
{1,2,3,5} - {1,2,3}
= {5}

2. H = {2,4,5}
K ={1,4,7}
L ={7,5,1}
(H-K) ◻ L
H-K = {2,4,5}-{1,4,7}
={1,2,5,7} ◻ L
= {1,2,5,7}◻ {7,5,1}
= {1,2,5,7}
= (H-K)
jadi, (H-K) ◻ L = (H-K)

5. Q U R = {BMW}
P ◻ (QUR)
= {Panther, Kijang, Honda, Suzuki}

7. a. A" = {6,7,8,9,10}
B ◻ C = {3,4,5,6,7,8,9}
{6,7,8,9,10} U {3,4,5,6,7,8,9}
= {6,7,8,9}
b. A ◻ B = {1,2,3,4,5,6,7,8}
C" = {1,2,4,6,8,10}
{1,2,3,4.5,6,7.8} U {1,2,4,6,8,10}
= {1,2,4,6,8}

c. B-C = {4,6,8}
A = {1,2,3,4,5}
{4,6,8}◻{1,2,3,4,5}
={1,2,3,4,5,6,8}

Answer 2

1.  A = ( 1,2,3 )
   B = ( 2,1,5 )
   maka A u B = ( 1, 2 )
   jika ( A u B ) - A = ( 1,2 ) - ( 1,2,3 )
                          =  ( ) = Ф = himp. kosong

2. H = ( 2,4,5 )                maka, ( H - K ) n L = ( ( 2,4,5 ) - ( 1,4,7 ) ) n ( 7,5,1 )
    K = ( 1,4,7 )                                            = ( 2,5 ) n ( 7,5,1 )
     L = ( 7,5,1 )                                           =  ( 5 )
