化简 (-5xy^2z)(7x^6y^2z-3x^5y-4xz)

解答

化简

(- 5 x y^{2} z) (7 x^{6} y^{2} z - 3 x^{5} y - 4 x z)

- 5 x y^{2} z (7 x^{6} y^{2} z - 3 x^{5} y - 4 x z)

求解步骤

(- 5 x y^{2} z) (7 x^{6} y^{2} z - 3 x^{5} y - 4 x z)

使用法则:

(- a) = - a

(- 5 x y^{2} z) = - 5 x y^{2} z

= - 5 x y^{2} z (7 x^{6} y^{2} z - 3 x^{5} y - 4 x z)

\frac{x ^{2} - 4 x}{16 - x ^{2}}

32 + 550

(2 a^{2} + 3 b) (2 a^{2} - 3 b)

\frac{x ^{3} - 27 y ^{3}}{x ^{2} - 9 y ^{2}}

x - (- 2 x + 4)
