Vì: \(\left(x-12+y\right)^{200}\ge0;\left(x-4-y\right)^{200}\ge0\)
=> \(\left(x-12+y\right)^{200}+\left(x-4-y\right)^{200}\le0\)
\(\Leftrightarrow\left(x-12+y\right)^{200}+\left(x-4-y\right)^{200}=0\)
\(\Leftrightarrow\begin{cases}x-12+y=0\\x-4-y=0\end{cases}\)\(\Leftrightarrow\begin{cases}x+y=12\\x-y=4\end{cases}\)\(\Leftrightarrow\begin{cases}x=8\\y=4\end{cases}\)
Tìm x,y,z
\(\left|x-3\right|+\left|y-2x\right|+\left|2z-x+y\right|=0\)
\(\left|x-y\right|+\left|2y+x-\frac{1}{2}\right|+\left|x+y+z\right|\le0\)
Tìm x sao cho
\(\left(x+1\right)^{200}=\left(2x-3\right)^{200}\)
\(\left(\dfrac{4}{7}y-1\right)^{2010}+\left(-\dfrac{2}{3}y+4\right)^{68}\le0\). Tìm x,y
Tìm x , y thõa mãn :
\(\left|x+\frac{8}{5}\right|+\left|2,2-2y\right|\le0\)
\(b.\left|\frac{3}{2}x+\frac{1}{9}\right|+\left|\frac{1}{5}y-\frac{1}{2}\right|\le0\)
Tìm x , y biết:
\(\left(2x-5\right)^{2016}+\left(3y+4\right)^{2020}\le0\)
Tìm số hữu tỉ x, y biết: \(\left(3x-33\right)^{2008}+\left|y-7\right|^{2009}\le0\)
Tìm x,y:
a,\(\left(x-\frac{1}{2}\right)^2+\left(\frac{3}{4}-y\right)^2=0\)
b,\(2^{x+1}.3^y=12^x\)
Tìm x , y biết:
\(\left(2x-\dfrac{1}{6}\right)^2+|3y+12|\le0\)
