簡約 (1/2 y)^2

解

簡約

(\frac{1}{2} y)^{2}

\frac{y ^{2}}{4}

解答ステップ

(\frac{1}{2} y)^{2}

指数の規則を適用する:

(a \cdot b)^{n} = a^{n} b^{n}

(\frac{1}{2} y)^{2} = (\frac{1}{2})^{2} y^{2}

= (\frac{1}{2})^{2} y^{2}

(\frac{1}{2})^{2} = \frac{1}{4}

= \frac{1}{4} y^{2}

簡素化

\frac{1}{4} y^{2} : \frac{y ^{2}}{4}

= \frac{y ^{2}}{4}
