a) 34 = 81
43 = 64
=> 34 > 43
b) 273 = (33)3 = 39
94 = (32)4 = 38
Vì 39 > 38
=> 273 > 94
c) 222333 = 2333 . 111333 = (23)111 . 111111 . 111222 = 8111 . 111111 . 111222 = 888111 . 111222
333222 = 3222 . 111222 = (32)111 . 111222 = 9111 . 111222
VÌ 888111 > 9111
=> 222333 > 333222
Ủng hộ mk nha ^_-
\(3^4=81\)
\(4^3=64\)
\(\Rightarrow3^4>4^3\)
