 Amigos da lista me uma ajuda nas seguintes quest=F5es:

  1) Se x =3D 1+ raiz quadrada(2004), ent=E3o 4x^3 - 2007x - 2005 =E9 =
igual a :

        a) 0                       b) 1            c) -1       d) 2      =
      e) -2

 2) Dado x^1 + x^ -1 =3D {1 + raiz qradrada(5)}/2. O valor de x^2000 + =
x^ -2000 =E9 igual a :
=20
 a)1                          b)2                         c){1 + raiz =
qradrada(5)}/2                       d)20


 3)Simplifique : { x^7 + y^7 + z^7}/xyz(x^4 + y^4 + z^4)
