Question

tolong bantuin aku ya besok di kumpulin dari no 1 sampe 5 aja.
tolong sekalian ya caranya pake tabel

Answer 1

1. 18, 42 dan 48

Menggunakan Faktorisasi

18 = 2 ``````x 3²

42 =2 ``````x 3 x 7

48 = 2^4 x 3

-----------------------

FPB = 2 x 3 = 6

KPK = 2^4 x 3² x 7 = 16 x 9 x 7 = 1.008

Menggunakan tabel

18, 42, 48

--------------2 FPB

FPB = 2 x 3 = 6

KPK = 2^4 x 3² x 7 = 16 x 9 x 7 = 1.008

2. 35, 40 dan 65

Menggunakan Faktor

35 = `````````5 x 7

40 = 2³ x 5

65 = `````````5 ``````````x 13

------------------------------

FPB = 5

KPK = 2³ x 5 x 7 x 13 = 8 x 5 x 7 x 13 = 3.640

Menggunakan Tabel

35, 40, 65

FPB = 5

KPK = 2³ x 5 x 7 x 13 = 8 x 5 x 7 x 13 = 3.640

3. 16, 28 dan 32

Menggunakan Faktor

16 = 2^4

28 = 2² x 7

32 = 2^5

--------------------

FPB = 2² = 4

KPK = 2^5 x 7 = 32 x 7 = 224

Menggunakan Tabel

16, 28, 32

KPK = 2^5 x 7 = 32 x 7 = 224

4. 45, 50 dan 60

Menggunakan Faktor

45 = ```````3² x 5

50 = 2 ````````x 5²

60 = 2² x 3 x 5

----------------------

FPB = 5

KPK = 2² x 3² x 5² = 4 x 9 x 25 = 900

Menggunakan Tabel

45, 50 , 60

FPB = 5

KPK = 2² x 3² x 5² = 4 x 9 x 25 = 900

5. 20, 18 dan 42

Menggunakan Faktor

20 = 2² ````x 5

18 = 2 x 3²

42 = 2 x 3 ``````x 7

-----------------------

FPB = 2

KPK = 2² x 3² x 5 x 7 = 4 x 9 x 5 x 7 = 1.260

Menggunakan Tabel

Answer 2

Verified answer

1. 18 = 2x3²
42 = 2x3x7
48 = 2pangkat4 x 3
FPB = 2x3 = 6
KPK = 2pangkat4 x 3²x 7 = 1008

2. 35 = 5x7
40 = 2³x5
65 = 5x13
FPB = 5
KPK = 2³x5x7x13 = 3340

3. 16 = 2pangkat4
28 = 2²x7
32 = 2pangkat5
FPB = 2²=4
KPK = 2pangkat5 x 7 = 224

4. 45 = 3²x5
50 = 2x5²
60 = 2²x3x5
FPB = 3x5= 15
KPK = 2²x3²x5² = 4x9x25= 900

5. 20 = 2²x5
18 = 2x3²
42 = 2x3x7
FPB = 2
KPK = 2²x3²x5x7 = 1180
