Tìm x, y
| x - 2017 | + | y - 2018 | ≤ 0
3| x - y |5 + 10| y + 2/3 |7 ≤ 0
1/2(3/4x - 1/2)2018 + 2017/2018|4/5 y+ 6/25| ≤ 0
2017 |2x - y | 2018 + 2018 | y - 4 |2017 ≤ 0
Tìm x , y thỏa mãn :
a) \(\frac{1}{2}\times(\frac{3}{4}x-\frac{1}{2})^{2018}+\frac{2017}{2018}\times/\frac{4}{5}y+\frac{6}{25}/\le0\)0
b) \(2017\times/2x-y/+2018\times(y-4)^{2017}\le0\)
Tìm x,y thõa mãn: /x-1/+/x-2017/+/y-2018/+/x-2018/=2017
Tìm x,y thỏa mãn:\(|x-1|+|x-2017|+|y-2018|+|x-2018|=2017\)
Tìm giá trị nhỏ nhất
P = 2018/x^2+2x+2017
Q = a^2018+2017/a^2018+2015
A = (x-3y)^2020+(y-2018)^2018
B = (x+y-5)^8+(x-2y)^4+2016
C = \x-2017\+\x-2018\
D = \x-2010\+\x-2011\+\x+2012\
Cho x,y>0 thỏa mãn
x^2015+y^2015=x^2016+y^2016=x^2017+y^2017
C/m: 1/x^2018+1/y^2018=1/x^2019+1/y^2019
cho x=2017 tính
y=f(x)=x5-2018*x4+2018*x3-2018*x2+2018*x-1
tìm x,y,z biết x+y+2017/z=y+z-2018/x=x+z+1/y
tìm x y thỏa mãn \(3|x-2017|+1=\frac{2}{|y-2018|+1}\)
