解

簡約

999.9999800000000 \dots (3.5 \cdot 1 0^{- 3})

3.49999993

解答ステップ

999.99998 (3.5 \cdot 1 0^{- 3})

1 0^{- 3} = \frac{1}{1000}

= 999.99998 \cdot 3.5 \cdot \frac{1}{1000}

3.5 \cdot \frac{1}{1000} = \frac{3.5}{1000}

= 999.99998 \cdot \frac{3.5}{1000}

数を割る:

\frac{3.5}{1000} = 0.0035

= 999.99998 \cdot 0.0035

数を乗じる:

999.99998 \cdot 0.0035 = 3.49999993

= 3.49999993
