Ta thấy: \(\begin{cases}\left(x-2\right)^{2012}\ge0\\\left|y^2-9\right|^{201}\ge0\end{cases}\)
\(\Rightarrow\left(x-2\right)^{2012}+\left|y^2-9\right|^{201}\ge0\)
\(\Rightarrow\left(x-2\right)^{2012}+\left|y^2-9\right|^{201}+5\ge5\)
\(\Rightarrow A\ge5\). Dấu "=" xảy ra khi
\(\begin{cases}\left(x-2\right)^{2012}=0\\\left|y^2-9\right|^{201}=0\end{cases}\)\(\Leftrightarrow\begin{cases}x-2=0\\y^2-9=0\end{cases}\)\(\Leftrightarrow\begin{cases}x=2\\y=\pm3\end{cases}\)
Vậy \(\begin{cases}x=2\\y=\pm3\end{cases}\)
