222333=2223.111=(2223)111=666111
333222=3332.111=(3332)111=666111
vì 666111=666111
=>222333=333222
222333 = (2.111)333
= 2333 . 111333
= 23.111 . 1113.111
= (23)111 . (1113)111
= 8111 . (1112.111)111
= 8111 . (1112)111 .111111
= 888111 . (1112)111
333222=(3.111)222
=3222 . 111222
=32.111 . 1112.111
= (32)111 . (1112)111
= 9111 . (1112)111
Mà 888111 . (1112)111 > 9111 . (1112)111 nên 222333 > 333222
222333 và 333222
222333 = (2223)111 = 666111
333222 = (3332)111 = 666111
Vì 666 = 666 nên 666111 = 666111
Vậy 222333 = 333222
