1.	Let A=⎡⎢⎣xyzyzxzxy⎤⎥⎦, where x,y and z are real numbers such that x+y+z>0 axyz=2. If A2=I3, then the value of x3+y3+z3 is
Answer» Let $A = ⎡ ⎢ ⎣ \begin{matrix} x & y & z y & z & x z & x & y \end{matrix} ⎤ ⎥ ⎦$ , where $x, y$ and $z$ are real numbers such that $x + y + z > 0$ a $x y z = 2$ . If $A^{2} = I_{3}$ , then the value of $x^{3} + y^{3} + z^{3}$ is
