化简 2.00273*10^{-9}(120)

解答

化简

2.00273 \cdot 1 0^{- 9} (120)

2.40328 E - 7

求解步骤

2.00273 \cdot 1 0^{- 9} (120)

使用法则:

(a) = a

(120) = 120

= 2.00273 \cdot 1 0^{- 9} \cdot 120

数字相乘:

2.00273 \cdot 120 = 240.3276

= 240.3276 \cdot 1 0^{- 9}

= 1 0^{- 9} \cdot 240.3276

使用指数法则:

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

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

= \frac{1}{1 0 ^{9}} \cdot 240.3276

1 0^{9} = 1000000000

= \frac{1}{1000000000} \cdot 240.3276

\frac{1}{1000000000} \cdot 240.3276 = \frac{240.3276}{1000000000}

= \frac{240.3276}{1000000000}

数字相除:

\frac{240.3276}{1000000000} = 2.40328 E - 7

= 2.40328 E - 7
