簡約 1/2 (0.5*10^{-6})(18.5)^2

解

簡約

\frac{1}{2} (0.5 \cdot 1 0^{- 6}) (18.5)^{2}

\frac{1369}{16000000}

十進法表記

0.0000855625

解答ステップ

\frac{1}{2} (0.5 \cdot 1 0^{- 6}) \cdot 18. 5^{2}

簡素化

0.5 \cdot 1 0^{- 6} : 0.0000005

= \frac{1}{2} \cdot 0.0000005 \cdot 18. 5^{2}

18. 5^{2} = 342.25

= \frac{1}{2} \cdot 0.0000005 \cdot 342.25

数を乗じる:

0.0000005 \cdot 342.25 = 0.000171125

= \frac{1}{2} \cdot 0.000171125

0.000171125 = \frac{1369}{8000000}

= \frac{1}{2} \cdot \frac{1369}{8000000}

\frac{1}{2} \cdot \frac{1369}{8000000} = \frac{1369}{16000000}

= \frac{1369}{16000000}
