化简 ((51.142)/(26315.79))*10^{-6}

解答

化简

(\frac{51.142}{26315.79}) \cdot 1 0^{- 6}

\frac{25571}{1.31579 E 13}

十进制

1.9434 E - 9

求解步骤

(\frac{51.142}{26315.79}) \cdot 1 0^{- 6}

\frac{51.142}{26315.79} = \frac{51142}{26315790}

= \frac{51142}{26315790} \cdot 1 0^{- 6}

消掉

\frac{51142}{26315790} : \frac{25571}{13157895}

= \frac{25571}{13157895} \cdot 1 0^{- 6}

使用指数法则:

a^{- b} = \frac{1}{a ^{b}}

1 0^{- 6} = \frac{1}{1 0 ^{6}}

= \frac{25571}{13157895} \cdot \frac{1}{1 0 ^{6}}

1 0^{6} = 1000000

= \frac{25571}{13157895} \cdot \frac{1}{1000000}

\frac{25571}{13157895} \cdot \frac{1}{1000000} = \frac{25571}{1.31579 E 13}

= \frac{25571}{1.31579 E 13}
