    System of equations

    Solve the system of equations:
    \left\{\begin{matrix}<br /> 2\sqrt[4]{\frac{x^4}{3}+4}=1+\sqrt{\frac{3}{2}.y^2}\\2\sqrt[4]{\frac{y^4}{3}+4}=1+\sqrt{\frac{3}{2}.x^2}\end{mat rix}\right.

    Hi Leezangqe, are both equations correctly posted? Cause \sqrt{\frac{3}{2}\times y^{2}} in the first equation could be \sqrt{\frac{3}{2}}y.

    @kylehk
    No, it is
    \sqrt{\frac{3}{2}\times y^{2}}= \sqrt{\frac{3}{2}}\left | y \right |

    first thoughts:
    As the equations are cyclic, maybe it would help to solve 2\sqrt[4]{\frac{x^4}{3}+4}=1+\sqrt{\frac{3}{2}}x first, because my best guess is that it will work for x=y.
    Would be great if anybody solves this equation...
