化简 0.284(2.5*10^{-13})

解答

化简

0.284 (2.5 \cdot 1 0^{- 13})

\frac{71}{1.0 E 15}

十进制

7.1 E - 14

求解步骤

0.284 (2.5 \cdot 1 0^{- 13})

使用指数法则:

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

1 0^{- 13} = \frac{1}{1 0 ^{13}}

= 0.284 \cdot 2.5 \cdot \frac{1}{1 0 ^{13}}

2.5 \cdot \frac{1}{1 0 ^{13}} = \frac{1}{4000000000000}

= 0.284 \cdot \frac{1}{4000000000000}

0.284 = \frac{71}{250}

= \frac{71}{250} \cdot \frac{1}{4000000000000}

\frac{71}{250} \cdot \frac{1}{4000000000000} = \frac{71}{1.0 E 15}

= \frac{71}{1.0 E 15}
