tentukanlah FPB dan KPK berikut a.24 dan 32 b.72 dan 216 c.45 dan 50 e.80dan 128 d.115 dan 125

A. 24 = 2^3 × 3
32 = 2^5
FPB = 2^3 = 2 × 2 × 2 = 8
KPK = 2^5 × 3 = 32 × 3 = 96
B. 72 = 2^3 × 3^2
216 = 2^3 × 3^3
FPB = 2^3 × 3^2 = 8 × 9 = 72
KPK = 2^3 × 3^3 = 8 × 27 = 216
C. 45 = 3^2 × 5
50 = 2 × 5^2
FPB = 5
KPK = 2 × 3^2 × 5^2 = ( 2 × 9 ) × 25 = 18 × 25 = 450
E. 80 = 2^4 × 5
128 = 2^7
FPB = 2^4 = 2 × 2 × 2 × 2 = 16
KPK = 2^7 × 5 = 128 × 5 = 640
D. 115 = 5 × 23
125 = 5^3
FPB = 5
KPK = 5^3 × 23 = 125 × 23 = 2.875

A. 24 = 2³ x 3
32 = 2 pangkat lima.
FPB = 2³ = 8
KPK= 2 pangkat lima x 3 = 32.

b. 72 = 2³ x 3²
216= 2³ x 3³
FPB = 2³ x 3² = 72
KPK = 2³ x 3³ = 216

C. 45 = 5 x 3²
50 = 2 x 5²
FBP = 5
KPK = 2 x 3² x 5² = 450

d. 80 = 2³ x 5
128 = 2 pangkat 7
FBP = 2³ = 8
KPK = 2 pangkat 7 x 5 = 128

E. 115 = 5 x 23
125 = 5³
FBP = 5
KPK = 5³ x 23 = 2.875
