解

簡約

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

2.99999994

解答ステップ

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

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

= 999.99998 \cdot 3 \cdot \frac{1}{1000}

3 \cdot \frac{1}{1000} = \frac{3}{1000}

= 999.99998 \cdot \frac{3}{1000}

999.99998 \cdot \frac{3}{1000} = \frac{2999.99994}{1000}

= \frac{2999.99994}{1000}

数を割る:

\frac{2999.99994}{1000} = 2.99999994

= 2.99999994
