555 + (-100 ) + ( - 80 ) + 333
= 555 - 100 - 80 + 333
= 455 - 80 + 333
= 375+ 333
= 708.

555 – (-333) – 100 – 80 = (555 + 333) –(100 + 80) = 888 – 180 = 708

333555 và 555333
= 333555 = ( 3.111 )555 = 3555 . 111555 = ( 45 )111 . 111555 = 1024111 . 111555
= 555333 = ( 5.111 )333 = 5333 . 111333 = ( 53 )111 . 111333 = 125111 . 111333
Vì 1024111 . 111555 > 125111 . 111333
\(\Rightarrow\)3555 > 555333
Đặt 333555 =A ; 555333 =B Ta có:
A=333555 =(3.111)5.111 =35.111 .1115.111
B=555333 = (5.111)3.111 = 53.111 .1113.111
Vậy.........
