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
a)2.16.8.4.32
=2^1.2^4.2^3.2^2.2^5
=2^15
b)9.27.81.729

d)36.30.125
=6^2.6.5.5^3
=6^3.5^4
a. 2. 16 . 8 . 4 . 32
= 2 .2 .8 .8 .4 . 4 .8
= \(^{2^2}\). \(8^3\). \(^{4^2}\)
Lời giải:
a.
$2^3.225.45=2^3.15^2.3^2.5=2^3.5^2.3^2.3^2.5$
$=2^3.3^4.5^3$
b.
$5.10.15.20=5.5.2.5.3.5.4=2.3.4.5^4=2.3.2^2.5^4=2^3.3.5^4$
