2. KPK dan FPB dari 120 dan 40 (pake cara sisir)
keterangan : bintang (*) untuk menandakan FPB
*2 | 120 - 40
*2 | 60 - 20
*2 | 30 - 10
3 | 15 - 5
*5 | 5 - 5
1 - 1
KPK 120 dan 40 => 2³ × 3 × 5 =120
FPB 120 dan 40 => 2³ × 5 = 40
3. 15 × (12 - 6) =15 × 6 = 90
4. 25 × (-10) × 2 = -500
5. bilangan kubik antara 100 sampai 200 adalah 125 (5³)
= 300 + 315 - 72
= 543
2. FPB = 120 = 2 x 3 x 5
= 40 = 2 pangkat 3 x 5
FPB = 2 pangkat 3 x 5 = 8 x 5 =40
Kpk = 2 pangkat3 x 3 x5 = 8x3x5 = 120
3. 15 x ( 12 -6)
15 x 6 = 90
4. 25x (-10) x 2
(-250)x 2 = -500
