Question

Timf x,y biết :

| x+5 | +(3y-4 ) ²⁰¹⁰ =0

Answer 1

\(\left|x+5\right|+\left(3y-4\right)^{2010}=0\)

Vì \(\left|x+5\right|\ge0\forall x\)

Vì \(\left(3y-4\right)^{2010}\ge0\forall y\)

\(\Rightarrow\left\{{}\begin{matrix}\left|x+5\right|=0\\\left(3y-4\right)^{2010}=0\end{matrix}\right.\)

\(\Rightarrow\left\{{}\begin{matrix}x+5=0\\3y-4=0\end{matrix}\right.\)

\(\Rightarrow\left\{{}\begin{matrix}x=-5\\y=\dfrac{4}{3}\end{matrix}\right.\)
