簡約 (sqrt(1-y^2))^3

解

簡約

(1 - y^{2})^{3}

(1 - y^{2}) 1 - y^{2}

解答ステップ

(1 - y^{2})^{3}

指数の規則を適用する:

a^{b + c} = a^{b} \cdot a^{c}

(1 - y^{2})^{2 + 1} = (1 - y^{2})^{2} 1 - y^{2}

= (1 - y^{2})^{2} 1 - y^{2}

指数の規則を適用する:

(n a)^{n} = a,

, 以下を想定

n i s o dd or a \geq 0

(1 - y^{2})^{2} = 1 - y^{2}

= (1 - y^{2}) 1 - y^{2}

= 1 - y^{2} (1 - y^{2})

= (1 - y^{2}) 1 - y^{2}
