Ta có : \(\left|2x-27\right|\ge0\forall x\Rightarrow\left|2x-27\right|^{2019}\ge0\forall x\)
\(\left(3x+10\right)^2\ge0\forall x\Rightarrow\left[\left(3x+10\right)^2\right]^{1009}=\left(3y+10\right)^{2018}\ge0\forall x\)
\(\Rightarrow\left|2x-27\right|^{2019}+\left(3y+10\right)^{2018}\ge0\forall x\)
Dấu " = " xảy ra \(\Leftrightarrow\left|2x-27\right|=\left(3y+10\right)=0\)
\(\Leftrightarrow\left\{{}\begin{matrix}x=\frac{27}{2}\\y=-\frac{10}{3}\end{matrix}\right.\)
