1. Contoh bilangan pangkat tiga 1 s.d 10
Dapat
ditulis
jadi, 1, 8, 27,64, 125, 216, 343, 512, 729 dan1000
disebut juga BILANGAN KUBIK
1 X 1 X 1 = 1
2 X 2 X 2 = 8
3 X 3 X 3 = 27
4 X 4 X 4 = 64
5 X 5 X 5 = 125
6 X 6 X 6 = 216
7 X 7 X 7 = 343
8 X 8 X 8 = 512
9 X 9 X 9 = 729
10 X 10 X 10 = 1000
13= 1
23
= 8
33
= 27
43 = 64
53
= 125
63
= 216
73
= 343
83 = 512
93 = 729
103
= 1000

2. 2 + 1 = 3
3 - 1 = 2

4. keliling
persegi panjang bujur sangkar segitiga
b=4cm b c
a=8cm a=6cm a
k = 8 + 5 + 8 + 5 k = 6 + 6 + 6 + 6 k = a + b + c
