1. Tulislah dalam bentuk tabular form ?
a. P = { x | x^ - 4x - 5 = 0}
b. Q = { x | x huruf dalam perkataan “masalah”}
c. R = { x | x2 = 16, 2x = -8}
d. S = { x | x adalah angka di dalam bilangan 132131}
Jawab:

a. P = {5}
b. Q = {m,a,s,l,h}
c. R = {-4}
d. S = {1,2,3}

2. Tentukan kardinal himpunan bagian A = {a,b,c,d} ?
Jawab:
B = {a, b, c, d} artinya n = 4 maka Kardinal = 24 = 16, yaitu:
{a}, {b}, {c}, {d}
{a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}
{a,b,c}, {a,b,d}, {b,c,d}, [c,d,a}
{a,b,c,d}, {}


3. Diketahui S = {b,d,e} A = {a,b,d} B = {b,d,e}, tentukan:
Jawab:
a. A U B = {a,b,d,e}
b. B n A = {b,d}
c. B’ = {}
d. B – A = {e}
e. A’ n B =
f. A U B’ = {a,b,d} U {} = {a,b,d}
g. A’ n B’ =
h. {A n B)’ = {b,d}’ = {e}
i. B’ – A’ =
j. {A U B)’ = {a,b,d,e}’ = {}
