簡約 (15/2)^2*1/75 (1-|0.3|)^2

解

簡約

(\frac{15}{2})^{2} \cdot \frac{1}{75} (1 - ∣ 0.3 ∣)^{2}

\frac{147}{400}

十進法表記

0.3675

解答ステップ

(\frac{15}{2})^{2} \frac{1}{75} (1 - ∣ 0.3 ∣)^{2}

(\frac{15}{2})^{2} = \frac{225}{4}

= \frac{225}{4} \cdot \frac{1}{75} (1 - ∣ 0.3 ∣)^{2}

1 - ∣ 0.3 ∣ = 0.7

= \frac{225}{4} \cdot \frac{1}{75} \cdot 0. 7^{2}

0. 7^{2} = 0.49

= \frac{225}{4} \cdot \frac{1}{75} \cdot 0.49

\frac{225}{4} \cdot \frac{1}{75} \cdot 0.49 = \frac{147}{400}

= \frac{147}{400}
