解

簡約

\frac{1}{2} + \frac{3}{44} (5 (0.6) - \frac{( 0.6 ) ^{3}}{3})

\frac{962}{1375}

十進法表記

0.69963 \dots

解答ステップ

\frac{1}{2} + \frac{3}{44} (5 (0.6) - \frac{0. 6 ^{3}}{3})

規則を適用する:

(a) = a

(0.6) = 0.6

= \frac{1}{2} + \frac{3}{44} (5 \cdot 0.6 - \frac{0. 6 ^{3}}{3})

\frac{3}{44} (5 \cdot 0.6 - \frac{0. 6 ^{3}}{3}) = \frac{549}{2750}

= \frac{1}{2} + \frac{549}{2750}

\frac{1}{2} + \frac{549}{2750} = \frac{962}{1375}

= \frac{962}{1375}
