99^99-(1,(3)-(5.2^3-(-7)^2+1/3+99^9.(27^4-81^3-99^90)))

Đáp án`+`Giải thích các bước giải:

`99^99-{1,(3)-[(5.2^3-(-7)^2+1/3+99^9.(27^4-81^3-99^90)]}`

`=99^99-{1,(3)-[(5.8-49+1/3+99^9.(3^12-3^12-99^90)]}`

`=99^99-{1,(3)-[(5.8-49+1/3-99^99)]}`

`=99^99-{1,(3)-5.8+49-1/3+99^99}`

`=99^99-1,(3)+5.8-49+1/3-99^99`

`=99^99-4/3+40-49+1/3-99^99`

`=99^99+(-4)/3+40+(-49)+1/3+(-99^99)`

`=[99^99+(-99^99)]+((-4)/3+1/3)+[40+(-49)]`

`=-10`
