tentukanlah fpb dan kpk berikut! a.24 dan 32 b.72dan216 c.45dan 50 d.80dan 128 e.115dan 125

semoga membantu dalam belajar

Jawaban :
A.  24 dan 32
24 = 2^3 . 3
32 = 2^5 

Fpb = 2^3 = 8
kpk = 2^5 . 3 = 32 . 3 =96

B . 72 dan 216
72 = 2^3 . 3^2
216 = 2^3 . 3^3

Fpb = 2^3 . 3^2 = 72
Kpk = 2^3. 3^3 = 216

C.  45 dan 50
45 = 3^2 . 5
50 = 2 . 5^2

Fpb = 5
Kpk = 2 . 3^2 . 5^2 = 450

D . 80 dan 128
80 = 2^4 . 5
128 = 2^7

Fpb = 2^4 = 16
Kpk = 2^7 . 5 = 128 . 5 = 640

E . 115 dan 125
115 = 5 . 23
125 = 5^3
Fpb = 5
Kpk = 5^3 . 23 = 125 . 23 = 2875

semoga bermanfaat
