thang Vinh ngu vay khong biet
1. \(\left(1-x\right)^2+\left(3-y\right)^2+\left(y^2-x-z\right)^2=0\)
2. \(\left(x-y+z^2\right)+\left(y-2\right)^2+\left(z+3\right)^2=0\)
Làm hộ mình 2 câu này
a, \(\left[x+1\right]^2+\left|y+1\right|=0\)
b, \(\left|x+7\right|+\left[y-2\right]^{2016}=0\)
Tim X:Y biet
\(\left(x-1\right)^2+\left(y-4\right)^2=0\)
tìm các số x,y,z \(\left(3x-5\right)^{2006}+\left(y^2-1\right)^{2008}+\left(x-z\right)^{2100}=0\)
\(a,-\frac{2}{3}.\left(x-\frac{1}{4}\right)=\frac{1}{3}.\left(2x+1\right)\)
\(b,\frac{1}{5}.2^x+\frac{1}{3}.2^{x+1}=\frac{1}{5}.2^7+\frac{1}{3}:2^8\)
\(c,\left(x-y^2+z\right)^2+\left(y-2\right)^2+\left(z+3\right)^2=0\)
Tim cac so x,y,z,t biet:
\(\frac{27}{4}=\frac{-x}{3}=\frac{3}{y^2}=\frac{\left(z+3\right)^3}{-4}=\frac{\left|t\right|-2}{8}\)
Trinh bai cach lanm ra he
Chứng minh rằng:
\(\left(y-z\right)^3.\left(1-x^3\right)+\left(z-x\right)^3.\left(1-y^3\right)+\left(x-y\right)^3.\left(1-z^3\right)=3\left(1-xyz\right)\left(x-y\right)\left(y-z\right)\left(z-x\right)\)
Tìm x,y,z biết \(\left(x-y^2+z\right)^2+\left(y-2\right)^2+\left(z+3\right)^2=0\)
1.Tìm x,y thuộc z:
a,\(\left|2-x\right|+2=x\)
b,\(x+7=\left|x-9\right|\)
2.Tìm x,y thuộc z:
a,\(\left|x+10\right|+\left|5-y\right|=0\)
b,\(\left|x-40\right|+\left|x-y+10\right|=0\)
c,\(\left|x+y-30\right|+\left|x-y-4\right|=0\)
d,\(\left|x+y-15\right|+\left|xy-56\right|=0\)
