18 + I = 10 + 12
18 + I = 22
I = 22 - 18
I = 4

A = {1, 2, 4, 8}
n(A) = 4
Himp bagian = 2^4 = 16

No. 8
n = 4

1. 1
1. 2. 1
1. 3. 3. 1
1. 4. 6. 4. 1

Jadi banyaknya himp bagian dgn 0 anggota = 1; dgn 1 anggota = 4; dgn 2 anggota = 6; dgn 3 anggota = 4; dgn 4 anggota = 1

No. 9
S = himpunan bilangan asli

No. 10
A^c = {3, 5, 6, 7, 8, 9}
B = {2, 4, 6, 8}

A^c irisan B = {6, 8}
