111+222+333+444+555+666+777+888+999=?
giúp mình câu này
tính (x+y+z)^999/x^222.y^333.z^444
111+222+333+...+888+999+1001+1003+1005
`=111 xx (1+2+3+...+9) + (1001+1003+1005)`
`=111 xx 45 + 3009`
`=4995 +3009`
`=8004`
111+333+888+666+777+999+444+555+222=???????????????????????????????????????????????????????????/
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
