Question

B. Tentukan FPB dari bilangan-bilangan berikut!
1. 40,20, dan 16 =
2. 82 dan 72 =
3. 92 dan 64 =
4. 35,45, dan 55 =
5. 28,16, dan 18 =

Answer 1

1. 40 = 2³ x 5, 20 = 2² x 5, 16 = 2^4 , maka FPB = 2³ = 8
2. 82 = 2 x 41, 72 = 2³ x 3² , FPB = 2
3. 92 = 2² x 23, 64 = 2^6, FPB = 2² = 4
4. 35 = 5 x 7, 45 = 3² x 5, 55 = 5 x 11, FPB = 5
5. 28 = 2² x 7, 16 = 2^4, 18 = 2 x 3², FPB = 2

Answer 2

Jawaban menurut saya =
1. 40, 20, dan 16 = 4
2. 82 dan 72 = 2
3. 92 dan 64 = 4
4. 35, 45, dan 55 = 5
5. 28, 16, dan 18 = 2
