Answer 2

1)

a) 5 . 5 . 5 . 5 . 5 . 5 = 5⁶

b) 6 . 6 . 6 . 3 . 2 = 6 . 6 . 6 . 6 = 6⁴

c) 2 . 2 . 2 . 3 . 3 = 2³ . 3²

d) 100 . 10 . 10 . 10 = 10 . 10 . 10 . 10 . 10 = 10⁵

2)

a) 2³ = 2 . 2 . 2 = 8

2⁴ = 2 . 2 . 2 . 2 = 16

2⁵ = 2 . 2 . 2 . 2 . 2 = 32

2⁶ = 2 . 2 . 2 . 2 . 2 . 2 = 64

2⁷ = 2 . 2 . 2 . 2 . 2 . 2 . 2 = 128

2⁸ = 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 = 256

2⁹ = 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 = 512

2¹⁰ = 2 . 2 . 2 . 2 . 2. . 2 . 2 . 2 . 2 . 2 = 1024

b) 3² = 3 . 3 = 9

3³ = 3 . 3 . 3. = 27

3⁴ = 3 . 3 . 3 . 3 = 81

3⁵ = 3 . 3 . 3 . 3 . 3 = 243

c) 4² = 4 . 4 = 16

4³ = 4 . 4 . 4 = 64

4⁴ = 4 . 4 . 4 . 4 = 256

d) 5² = 5 . 5 = 25

5³ = 5 . 5 . 5 = 125

5⁴ = 5 . 5 . 5 . 5 = 625

e) 6² = 6 . 6 = 36

6³ = 6 . 6 . 6 = 216

6⁴ = 6 . 6 . 6 . 6 = 1296

Answer 3

a) 5.5.5.5.5.5=5\(^6\)

b)6.6.6.3.2=6.6.6.6 = 6\(^4\)(vi 3.2 bang 6 nha)

c)2.2.2.3.3=2\(^3\).3\(^2\)

d) 100.10.10.10=10.10.10.10.10=10\(^5\)  (vi 100 tach ra bang 10.10)
