Ta có: x^2017=x^2017-2/3
<=> x^2017-x^2017=2/3
<=> 0=2/3 (vô lý)
Vậy ko có x thỏa mãn

Tìm x,y thoả mãn
/x-2017/+/y-2018/ <=0
/3.x-y/^5+10./y+2/3/^7 <=0

d,2017./2x-y/^2018+2018./y-4/^2017<=0
giúp em vs m.n ưi,mai em nộp ùi
Tìm x khi biết x:☺
\(\left(\frac{x-4}{2017}\right)+\left(\frac{x-3}{2018}\right)+\left(\frac{x-2}{2019}\right)+\left(\frac{x-1}{2020}\right)=4\)
gip mik với mik cần gấppppppppppppppppp
1. (x - 2)2016 + |y2 - 9|2017 = 0
2. |x - 3,2| + |2x - 1/5| = x+3
giúp mình vs mình tick cho
Tìm x:
a) (x-3)3=3-x
b) (x-2017)3 + 2017 = x
|x+1|+|x+2|+|x+3|+...........+|x+2017|=2018x
x+1/2020 + x+2/2019 + x+3/2018 + x+4/2017
Tính x^2015 + y^2016 + z^2017. Biết x + y + z = x^2 +y ^2 + z^2 = x^3 + y^3 + z^3
| x + 2017 | - x 2017 = x
- | x + 2006 | - 2006 = x
x-2017/2019 + x-2019/2017 = x+6/2021
