化简 (4.5x10^{-2})/(8.3x10^4)

解答

化简

\frac{4.5 x 1 0 ^{- 2}}{8.3 x 1 0 ^{4}}

\frac{9}{16600000}

十进制

5.42169 E - 7

求解步骤

\frac{4.5 x \cdot 1 0 ^{- 2}}{8.3 x \cdot 1 0 ^{4}}

约分:

x

= \frac{4.5 \cdot 1 0 ^{- 2}}{8.3 \cdot 1 0 ^{4}}

\frac{1 0 ^{- 2}}{1 0 ^{4}} = \frac{1}{1 0 ^{6}}

= \frac{4.5}{8.3 \cdot 1 0 ^{6}}

\frac{4.5}{8.3 \cdot 1 0 ^{6}} = \frac{9}{16600000}

= \frac{9}{16600000}
