(1+2+3+...+100).(1^2+2^2+3^2+...+100^2).(65.111-13.15.37) 3.4^2-2^2.3

Đáp án + Giải thích các bước giải:

`(1+2+3+...+100).(1^2+2^2+3^2+...+100^2).(65.111-13.15.37)`

`= (1+2+3+...+100).(1^2+2^2+3^2+...+100^2).(7215-7215)`

`= (1+2+3+...+100).(1^2+2^2+3^2+...+100^2).0`

`= 0`

_____________________________________________________________________

`3.4^2 - 2^2 . 3`

`= 3 . (4^2 - 2^2)`

`= 3.12`

`= 36`
