(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2.................999 x 2 x 2 x 2 ?

A.(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2 > 999 x 2 x 2 x 2 = 9990 > 7992

B.(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2 < 999 x 2 x 2 x 2 = 9990 < 7992

C.(111 + 222 + 333 + 444 + 555 + 666 + 777 + 888 + 999)x 2 = 999 x 2 x 2 x 2 = 9990 = 7992

đúng k bạn 

chúc bn học tốt

222 + 222 = 444

555 + 555 = 1110

999 + 999 = 1998

222 + 222 = 444

555 + 555 = 1110

999 + 999 = 1998

222 + 222 = 444

555 + 555 = 1110

999 + 999 = 1998

 111 + 333 + 666 + 777 +999 +444 + 555 +222

=(111+999) + (333+777) + (666 + 444) +(555+ 222)

=1110 + 1110+1110 + 777

=1110 * 3 + 777

= 3330+ 777=4107

= 4885 nha tk mk nhé , xin bn lun đó

111 + 333 + 888 + 666 + 777 + 999 + 444 + 555 + 222 = 4995

bằng 4995 nha

\(999+888+777+666+555+444+333+222+111\)

\(=\left(999+111\right)+\left(888+222\right)+\left(777+333\right)+\left(666+444\right)+555\)

\(=1110+1110+1110+1110+555\)

\(=\left(1110\times4\right)+555\)

\(=4440+555\)
