化简-16x^3y^2(-4x^2y^4)

解答

化简

- 16 x^{3} y^{2} (- 4 x^{2} y^{4})

64 x^{5} y^{6}

求解步骤

- 16 x^{3} y^{2} (- 4 x^{2} y^{4})

使用法则:

- a (- b) = ab

- 16 x^{3} y^{2} (- 4 x^{2} y^{4}) = 16 x^{3} y^{2} \cdot 4 x^{2} y^{4}

= 16 x^{3} y^{2} \cdot 4 x^{2} y^{4}

数字相乘:

16 \cdot 4 = 64

= 64 x^{3} y^{2} x^{2} y^{4}

化简

x^{3} x^{2} : x^{5}

= 64 x^{5} y^{2} y^{4}

化简

y^{2} y^{4} : y^{6}

= 64 x^{5} y^{6}

e x p an d 5 x y (2 x - y) + 6 y^{2} (x^{2} + 6)

e x p an d (3 x - 4) (x + 2)
