Answer 1

Respuesta:

Explicación paso a paso:

(8x^4-7x^2y^4)^3

=(8x4−7x2y4)*(8x4−7x2y4)*(8x4−7x2y4)

=(8x4+−7x2y4)(49x4y8+−112x6y4+64x8)

=(8x4)(49x4y8)+(8x4)(−112x6y4)+(8x4)(64x8)+(−7x2y4)(49x4y8)+(−7x2y4)(−112x6y4)+(−7x2y4)(64x8)

=392x8y8−896x10y4+512x12−343x6y12+784x8y8−448x10y4

=−343x6y12+1176x8y8−1344x10y4+512x12
