Question

Tolong dijawab ya no 8 sampai12

Answer 1

== Nomor 8 ==

72 = 2³ × 3²
108 = 2² × 3³
FPB = 2² × 3² = 36
Faktorisasi prima dari 36 = 2² × 3² (B)

== Nomor 9 ==

24 = 2³ × 3
36 = 2² × 3²
60 = 2² × 3 × 5
KPK = 2³ × 3² × 5 = 360 (C)

== Nomor 10 ==

6 = 2 × 3
8 = 2³
4 = 2²
KPK = 2³ × 3 = 24
24 + 3 February = 27 February 2015

== Nomor 11 ==

48 = 2^4 × 3
56 = 2³ × 7
FPB = 2³ = 8 (D)

== Nomor 12 ==
= (27)² - 16²
= 729 - 256
= 473 (D)

Answer 2

8.72=2*2*2*3*3
108=2*2*3*3*3
FPB=2*2*3*3(B)
9.24=2*2*2*3
36=2*2*3*3
60=2*2*3*5
KPK=2*2*2*3*3*5=8*9*5=40*9=360
10.6=2*3
8=2*2*2
4=2*2
KPK=2*2*2*3=8*3=24
24HARI SETELAH SELASA,3 FEBRUARI 2015 ADALAH JUMAT,27 FEBRUARI 2015(A)
11.48=2*2*2*2*3
56=2*2*2*7
FPB=2*2*2=8(D)
12.(22+5)²-16²=27²-16²
=729-256=473(D)
