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

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
3) 2 + 22= 2 + 2.2 = 2 .( 1+2 ) = 2. 3
