解答ステップ

3.5 \cdot 1 0^{- 3} \cdot 68.4 6^{0.66}

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

= 3.5 \cdot \frac{1}{1000} \cdot 68.4 6^{0.66}

3.5 \cdot \frac{1}{1000} \cdot 68.4 6^{0.66} = \frac{3.5}{1000} \cdot 68.4 6^{0.66}

= \frac{3.5}{1000} \cdot 68.4 6^{0.66}

数を割る:

\frac{3.5}{1000} = 0.0035

= 0.0035 \cdot 68.4 6^{0.66}
