#Maaf yh klo jawabanny salah

1. 64 = 2pangkat6
80 = 2pangkat4 x 5
FPB = 2pangkat4 = 16
KPK= 2pangkat6 x 5 = 320
2. 30 = 2 x 3 x 5
60 = 2² x 3 x 5
FPB = 2 x 3 x 5 = 30
KPK = 2² x 3 x 5 = 60
3. 75 = 3 x 5²
48 = 2³ x 6
FPB = 1
KPK = 2³ x 3 x 5² x 6 = 3.600
4. 84 = 2² x 3 x 7
100 = 2² x 5²
FPB = 2² = 4
KPK = 2² x 3 x 5 x 7 = 420
5. 60 = 2² x 3 x 5
120 = 2³ x 3 x 5
FPB = 2² x 3 x 5 = 60
KPK = 2³ x 3 x 5 = 120
