Trả lời:
a, 5 . 125 . 625 = 5 . 53 . 54 = 58
b, 84 . 165 . 32 = ( 23 )4 . ( 24 )5 . 25 = 212 . 220 . 25 = 237
c, 274 . 8110 = ( 33 )4 . ( 34 )10 = 312 . 340 = 352
a) 5 . 125 . 625 = 5 . 53 . 54 = 51 + 3 + 4 = 58
b) 84 . 165 . 32 = 212 . 220 . 25 = 212 + 20 + 5 = 237
c) 274 . 8110 = 312 . 340 = 312 + 40 = 352
a, 5 . 125 . 625
= 5 . 53 . 54
= 51 + 3 + 4 = 58
b, 84 . 165 . 32
= (23)4 . (24)5 . 25
= 212 . 220 . 25
= 212 + 20 + 5 = 237
c, 274 . 8110
= (33)4 . (34)10
= 312 . 340
= 312 + 40 = 352
