解

簡約

12 x^{4} (- \frac{5}{6} x^{3} y^{2})

- 10 x^{7} y^{2}

解答ステップ

12 x^{4} (- \frac{5}{6} x^{3} y^{2})

規則を適用する:

a (- b) = - ab

12 x^{4} (- \frac{5}{6} x^{3} y^{2}) = - 12 x^{4} \frac{5}{6} x^{3} y^{2}

= - 12 x^{4} \frac{5}{6} x^{3} y^{2}

簡素化

x^{4} x^{3} : x^{7}

= - 12 x^{7} \frac{5}{6} y^{2}

簡素化

- 12 x^{7} \frac{5}{6} y^{2} : - 10 x^{7} y^{2}

= - 10 x^{7} y^{2}
