\(\left|x-y\right|+\left|y+\frac{9}{25}\right|=0\)
\(\left[\begin{matrix}\left|y+\frac{9}{25}\right|=0\\\left|x-y\right|=0\end{matrix}\right.\Rightarrow\left[\begin{matrix}y+\frac{9}{25}=0\\x-y=0\end{matrix}\right.\Rightarrow\left[\begin{matrix}y=\frac{-9}{25}\left(loại\right)\\x=y=\frac{-9}{25}\left(loại\right)\end{matrix}\right.\)
Vậy không có giá trị x, y thỏa mãn
1) Tìm x;y thuộc Z thỏa :
\(\left(x-2\right)^2+\left(y+16\right)^{2016}=0\)
Tìm x;y \(\in\) Z
\(\left|3x+2y\right|\) +\(\left|4y-1\right|\) \(\le\) 0
\(\left|x+y-7\right|\) \(\left|xy-10\right|\) \(\le\) 0
\(\left|x-y-2\right|\) +\(\left|y+3\right|\) =0
Tìm x ; y \(\in\) Z :
\(\left|x+2\right|\) +\(\left|y-4\right|\) = 0
Tìm \(x,y\in Z\) biết \(\left(x+5\right)^2.\left(y-2\right)=8\)
Tìm x;y \(\in\) Z
\(\left|3x-4\right|\) +\(\left|3y+5\right|\) =0
\(\left|x-3y\right|^{2007}\) +\(\left|y+4\right|^{2008}\) =0
\(\left(x+y\right)^{2006}\) +2007\(\left|y-1\right|\) =0
\(\left|x-y-5\right|\) + 2007\(\left|y-3\right|^{2008}\) =0
1.Tìm x,y
a)\(\left|x\right|\)=2017
b)\(\left|x\right|\)=\(\left|2017\right|\)
c)\(\left|x\right|\)+\(\left|y\right|\)=0
d)\(\left|x+5\right|\)+\(\left|y-3\right|\)=0
f)\(\left|x+2\right|\)=\(-5\)
1)tìm x\(\in\)Q biết:
a)\(\left(5\cdot x+1\right)^2=\dfrac{36}{49}\)
2)tìm x,y biết:
a)\(x^2+\left(y-\dfrac{1}{10}\right)^4=0\)
b)\(\left(\dfrac{1}{2}x-5\right)^{20}+\left(y^2-\dfrac{1}{4}\right)^{40}\le0\)
Bài 1: Tìm x, y biết :
\(\left|x+123\right|+|\left|y+1\right|-5|=0\)
