# Is it really hard?

Algebra Level 5

$\large{\begin{cases} x&+&y&+&z&=& 0 \\ x^3 &+& y^3 &+& z^3& =& 18 \\ x^7 &+& y^7 &+ &z^7 &=& 2058 \end{cases}}$

If $$x,y$$ and $$z$$ are complex numbers that satisfy the system of equations above and $$x^2 + y^2 + z^2 > 0$$, find the value of $$x^{10} + y^{10} + z^{10}$$.
