化简 (2xy)^2(-3x^2)(4y^2)

解答

化简

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

解答

- 48 x^{4} y^{4}

求解步骤

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

使用法则:

a (- b) = - ab

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

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

数字相乘:

3 \cdot 4 = 12

= - (2 x y)^{2} \cdot 12 x^{2} y^{2}

= - 12 (2 x y)^{2} x^{2} y^{2}

化简

(2 x y)^{2} : 4 x^{2} y^{2}

= - 12 \cdot 4 x^{2} y^{2} x^{2} y^{2}

数字相乘:

- 12 \cdot 4 = - 48

= - 48 x^{2} y^{2} x^{2} y^{2}

化简

x^{2} x^{2} : x^{4}

= - 48 x^{4} y^{2} y^{2}

化简

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

= - 48 x^{4} y^{4}
