已知实数xyz满足4x^2/1+4x^2=y,4y^2/1+4y^2=z,4z^2/1+4z^2=x,求xyz的值为什么
已知实数xyz满足4x^2/1+4x^2=y,4y^2/1+4y^2=z,4z^2/1+4z^2=x,求xyz的值
为什么
已知实数xyz满足4x^2/1+4x^2=y,4y^2/1+4y^2=z,4z^2/1+4z^2=x,求xyz的值为什么
(1)“已知实数x,y,z满足4x²/(1+4x²)=y,4y²/(1+4y²)=z,4z²/(1+4z²)=x,求x,y,z的值.
(2):“已知实数x,y,z满足(1+4x²)/4x²=y,(1+4y²)/4y²=z,(1+4z²)/4z²=x,求x,y,z的值.”
你的题目是(1)还是 (2)那样啊
都为0
x y z 不可能为负,当x增加时 f(x)显然增加。不妨设x>=y>=z
故f(x)>=f(y)>=f(z)
y>=z>=x
故x=y=z =1/2
