簡約 (-xy)^2*(2x^9y^5)^4

解

簡約

(- x y)^{2} \cdot (2 x^{9} y^{5})^{4}

16 x^{38} y^{22}

解答ステップ

(- x y)^{2} (2 x^{9} y^{5})^{4}

簡素化

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

= x^{2} y^{2} (2 x^{9} y^{5})^{4}

簡素化

(2 x^{9} y^{5})^{4} : 16 x^{36} y^{20}

= x^{2} y^{2} \cdot 16 x^{36} y^{20}

簡素化

x^{2} x^{36} : x^{38}

= x^{38} y^{2} \cdot 16 y^{20}

簡素化

y^{2} y^{20} : y^{22}

= x^{38} y^{22} \cdot 16

= 16 x^{38} y^{22}
