tim cac so x,y,z thoa man dang thuc :
\(\sqrt{\left(x-\sqrt{2}\right)^2}+\sqrt{\left(y+\sqrt{2}\right)^2}+Ix+y+zI=0\)
tìm các số x,y,z thỏa mãn đẳng thức :
\(\sqrt{\left(x-\sqrt{2}\right)^2}+\sqrt{\left(y+\sqrt{2}\right)^2}+Ix+y+zI=0\)
tim x biet
\(\sqrt{\left(x-\sqrt{2}\right)^2}+\sqrt{\left(y-\sqrt{2}\right)^2}+\left|x+y+z\right|=0\)
tim x,y,z biet \(\sqrt{\left(x-\sqrt{5}\right)^2}+\sqrt{\left(y+\sqrt{3}\right)^2}+\left|x-y-z\right|\)
\(\sqrt{\left(x-2\right)^2}+\sqrt{\left(y+2\right)^2}+\left|x+y+z\right|=0\)
tim x,y,z
Tìm các số x,y,z thỏa mãn đẳng thức:\(\sqrt{\left(x-\sqrt{2}\right)^2}+\sqrt{\left(y+\sqrt{2}\right)^2}+\left|x+y+z\right|=0\)| = 0
Tìm x;y;z biết \(\sqrt{\left(x-\sqrt{2}\right)^2}+\sqrt{\left(y+\sqrt{2}\right)^2}+\left|x+y+z\right|=0\)
\(\sqrt{\left(x-\sqrt{2}^2\right)}+\sqrt{\left(y+\sqrt{2}^2\right)}+\left|x+y+z\right|=0\)
