Respuesta:
[tex]x^{4}[/tex] = -4 [tex]x^{4}[/tex] = +1
Explicación paso a paso:
[tex]x^{8} + 3x^{4} -4 =0[/tex]
([tex]x^{4}[/tex] + 4) ([tex]x^{4}[/tex] - 1) = 0
[tex]x^{4}[/tex] + 4 = 0 l [tex]x^{4}[/tex] - 1 = 0
[tex]x^{4}[/tex] = 0 -4 l [tex]x^{4}[/tex] = 0 +1
[tex]x^{4}[/tex] = -4 l [tex]x^{4}[/tex] = +1
