A. Write out the indicated sets by listing their elements between braces.
1. Suppose A = {1,2,3,4} and B = {a,c).
(a) A x B
(c) A x A
(e) ox B
(g) A x (B x B)
(b) B x A
(d) B x B
(f) (A x B) x B
(h) B3
2. Suppose A = {n, e,0} and B = {0, 1}.
(a) A xB
(c) A x A
(e) Axo
(g) A x (B x B)
(b) B x A
(d) B x B
(f) (A x B) x B
(h) A x B x B
3. {xER: x2 = 2 x {a, c,e}
6. (xER: x2 = x x xEN: x2=x}
4. {nEZ:2<n <5) x {nez: In|=5}
7. {} x 10, 0} x {0, 1
5. {xER: x2 = 2 x {x ER: |x] =2)
8. {0, 14

( 4. ) InEz : 2 < < s / x fnez: In1= 5/
here, in is integer . so between 2 and 5 the
integers are 13,47 and since mod ( n ) = 5 .
means the value of n com be - 5 and +5
which becomes,
(3, 46...
