ta có : \(4^3.3^7.12^6.9^3.8^2=\left(2^2\right)^3.3^7.\left(2^2.3\right)^6.\left(3^2\right)^3.\left(2^3\right)^2\)
= \(2^6.3^7.2^{12}.3^6.3^6.2^6=2^{24}.3^{19}\)
\(4^3.3^7.12^6.9^3.8^2=2^6.3^7.2^{12}.3^6.3^6.2^6=2^{24}.3^{19}\)
Đề này là chịu rồi
Ta có: 43 . 37 . 126 . 93 . 82
= (22)3 . 37 . (4 . 3)6 . (32)3 . (23)2
= 26 . 37 . 46 . 36 . 36 . 26
= 26 . 37 . (22)6 . 36 . 36 . 26
= 26 . 37 . 212 . 36 . 36 . 26
= (26 . 212 . 26) . (37 . 36 . 36)
= 224 . 319
Chuk pạn hok tốt! 
43 . 37 . 126 . 93 . 82
= ( 22 )3 . 37 . ( 3 . 22 )6 . ( 32 )3 . ( 23 )2
