M = {2, 3, 4, 5, 6}
Himpunan bagian dari M = {}, {2}, {3}, {4}, {5}, {6}, {2, 3}, {2, 4}, {2, 5}, {2, 6}, {3, 4}, {3, 5}, {3, 6}, {4, 5}, {4, 6}, {5, 6}, {2, 3, 4}, {2, 3, 5}, {2, 3, 6}, {2, 4, 5}, {2, 4, 6}, {2, 5, 6}, {3, 4, 5}, {3, 4, 6}, {3, 5, 6}, {4, 5, 6}, {2, 3, 4, 5}, {2, 3, 4, 6}, {2, 3, 5, 6}, {2, 4, 5, 6}, {3, 4, 5, 6}, {2, 3, 4, 5, 6}.

3. Tentukan himpunan kuasa dari himpunan berikut.
a. A = {1, 2, 3, 4}
Penyelesaian:

A = {1, 2, 3, 4}
n(A) = 4

Himpunan kuasa A (P(A)) = {}, {1}, {2}, {3}, {4}, {1, 2}, {1, 3}, {1, 4}, {2, 3}, {2, 4}, {3, 4}, {1, 2, 3}, {1, 2, 4}, {1, 3, 4}, {2, 3, 4}, {1, 2, 3, 4}.
n(P(A)) = 2^4 = 16

b. B = {1, 2, 3, 4, 5}
Penyelesaian:

B = {1, 2, 3, 4, 5}
n(B) = 5
Jumlah himpunan kuasa B (n(P(B)) = 2^5 = 32

c. C = {1, 2, ..., 7, 8}
Penyelesaian:

C ={1, 2, ..., 7, 8}
