\(\left|2x-3y\right|^{999}+\left(5y-2z\right)^{1000}=0\)
\(\Rightarrow\left\{{}\begin{matrix}\left|2x-3y\right|^{999}=0\\\left(5y-2z\right)^{1000}=0\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}\left|2x-3y\right|=0\\5y-2z=0\end{matrix}\right.\)\(\Rightarrow\left\{{}\begin{matrix}2x-3y=0\\5y=2z\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}2x=3y\\\dfrac{y}{2}=\dfrac{z}{5}\end{matrix}\right.\)\(\Rightarrow\left\{{}\begin{matrix}\dfrac{x}{3}=\dfrac{y}{2}\\\dfrac{y}{2}=\dfrac{z}{5}\end{matrix}\right.\)
\(\Rightarrow\dfrac{x}{3}=\dfrac{y}{2}=\dfrac{z}{5}\)
Vậy với \(\forall x;y;z\in R\) sao cho \(\dfrac{x}{3}=\dfrac{y}{2}=\dfrac{z}{5}\) thì \(\left|2x-3y\right|^{999}+\left(5y-2z\right)^{1000}=0\)
