簡約 (-3x^2y^3)(5x^0y^2)

解

簡約

(- 3 x^{2} y^{3}) (5 x^{0} y^{2})

- 15 x^{2} y^{5}

解答ステップ

(- 3 x^{2} y^{3}) (5 x^{0} y^{2})

規則を適用する:

(- a) = - a

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

= - 3 x^{2} y^{3} \cdot 5 x^{0} y^{2}

数を乗じる:

- 3 \cdot 5 = - 15

= - 15 x^{2} y^{3} x^{0} y^{2}

簡素化

x^{2} x^{0} : x^{2}

= - 15 x^{2} y^{3} y^{2}

簡素化

y^{3} y^{2} : y^{5}

= - 15 x^{2} y^{5}
