\(\left|3x-0,\left(36\right)\right|+\left|5y+1,2\left(18\right)\right|=0\)
Có: \(\left|3x-0,\left(36\right)\right|\ge0,\forall x\)
\(\left|5y+1,2\left(18\right)\right|\ge0,\forall y\)
=>\(\left|3x-0,\left(36\right)\right|+\left|5y+1,2\left(18\right)\right|\ge0;\forall x,y\)
Dấu "=" xảy ra: \(\hept{\begin{cases}3x-0,\left(36\right)=0\\5y+1,2\left(18\right)=0\end{cases}\Leftrightarrow}\hept{\begin{cases}x=0,\left(12\right)\\y=0,24\left(36\right)\end{cases}}\)
