Let \(\alpha\) and \(\beta\) be the two roots of the quadratic equation \[x^2-mx+n=0,\] and \(\alpha+\beta\) and \(\alpha\beta\) be the two roots of the quadratic equation \[x^2-8x+1=0.\] Then what is the value of \(m^3+n^3 ?\)
Let \(\alpha\) and \(\beta\) be the two roots of the quadration \[x^2-2x-2=0.\] If the quadratic equation whose two roots are \(\alpha^3\) and \(\beta^3\) can be expressed as \(x^2+ax+b=0,\) what is the value of \(3ab?\)
