[tex](x-3)(x+3)( x^{2}+9)( x^{4} +81)( x^{8}+3^{8})= x^{16}-3^{16}
(x-3)(x+3)= x^{2}+3x-3x-9= x^{2}-9
(x^{2}-9)( x^{2}+9)= x^{4}+9 x^{2}- 9x^{2}-81= x^{4} -81
(x^{4}-81)( x^{4}+81)= x^{8}+81 x^{4}-81 x^{4}-6561= x^{8}-6561
(x^{8}-6561)( x^{8}+6561)= x^{16}+6561 x^{8}-6561 x^{8}- 3^{16} = x^{16}- 3^{16}
REZULTAT x^{16}- 3^{16} = x^{16}- 3^{16} (ADEV)[/tex]
