解

簡約

\frac{1}{2} + \frac{3}{32} (4 \cdot 1.1 - \frac{1. 1 ^{3}}{3})

0.87090625

解答ステップ

\frac{1}{2} + \frac{3}{32} (4 \cdot 1.1 - \frac{1. 1 ^{3}}{3})

\frac{3}{32} (4 \cdot 1.1 - \frac{1. 1 ^{3}}{3}) = 3.95633 \dots \cdot \frac{3}{32}

= \frac{1}{2} + 3.95633 \dots \cdot \frac{3}{32}

\frac{3}{32} \cdot 3.95633 \dots = 0.37090625

= \frac{1}{2} + 0.37090625

元を10進法形式に変換する

\frac{1}{2} = 0.5

= 0.5 + 0.37090625

数を足す:

0.5 + 0.37090625 = 0.87090625

= 0.87090625
