解答ステップ

6.8 \cdot 1 0^{- 9} \cdot 2^{4.7}

1 0^{- 9} = \frac{1}{1000000000}

= 6.8 \cdot \frac{1}{1000000000} \cdot 2^{4.7}

6.8 \cdot \frac{1}{1000000000} \cdot 2^{4.7} = \frac{6.8}{1000000000} \cdot 2^{4.7}

= \frac{6.8}{1000000000} \cdot 2^{4.7}

数を割る:

\frac{6.8}{1000000000} = 0.0000000068

= 0.0000000068 \cdot 2^{4.7}
