0 : 999 x 9 + 2345 - 567 : 12 - 678=
x-12*5*9+567=1000
x-540+567=1000 x-540=1000-567=432 x=540+432=972
\(x-12\times5\times9+567=1000\)
\(\Leftrightarrow x-540+567=1000\)
\(\Leftrightarrow x=1000-567+540\)
\(\Leftrightarrow x=973\)
Vậy x = 973.

x - 12x5x9 + 567 = 1000
x - 540 + 567 = 1000
x - 540 = 1000 - 567
x - 540 = 433
x = 433 + 540
x = 937

a) B = 2016 x 2016 - 2014 x 2018
b) 327 x 412 + 400 / 328 x 412 -12
c) ( 1234 x 567 - 667 ) : ( 567 + 1234 x 5
1 a/ B = 2016 . 2016 - 2014 . 2018
=\(2016^2-\left(2016-2\right).\left(2016+2\right)\)
= \(2016^2-2016.\left(-2+2\right)\\\)
=\(2016^2-2016.0 \)
= \(2016^2\)
1: Tính
a) B = 2016 x 2016 - 2014 x 2018
= (2016 x 2016) - (2014 x 2018)
= 4064256 - 4064252
= 4
b) 327 x 412 + 400 / 328 x 412 -12
= (327 x 412 + 400) / ( 328 x 412 - 12)
= 135124 / 135124
= 1
c) ( 1234 x 567 - 667 ) : ( 567 + 1234 x 5)
= (1234 x 567 - 667) : (567 + 1234 x 566)
= [1234 x 566 + (1234 - 667)] / (1234 x 566 + 567)
= (1234 x 566 + 567) / (1234 x 566 + 567)
