Question

tìm x y thỏa mãn : /2x-2011/ + (3y +2012)^2012 =0

Answer 1

\(\left|2x-2011\right|+\left(3y+2012\right)^{2012}=0\)

Vì \(\left|2x-2011\right|\ge0,\left(3y+2012\right)^{2012}\ge0\)

\(\Rightarrow\left|2x-2011\right|+\left(3y+2012\right)^{2012}\ge0\)

Mà \(\left|2x-2011\right|+\left(3y+2012\right)^{2012}=0\)

\(\Rightarrow\left\{{}\begin{matrix}2x-2011=0\\3y+2012=0\end{matrix}\right.\\ \Rightarrow\left\{{}\begin{matrix}x=\dfrac{2011}{2}\\y=-\dfrac{2012}{3}\end{matrix}\right.\)
