化简 e^{-1.6}*(1.6^4)/(4!)

解答

化简

e^{- 1.6} \cdot \frac{1. 6 ^{4}}{4 !}

0.05513 \dots

求解步骤

e^{- 1.6} \frac{1. 6 ^{4}}{4 !}

使用指数法则:

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

= \frac{1}{e ^{1.6}} \cdot \frac{1. 6 ^{4}}{4 !}

分式相乘:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{1 \cdot 1. 6 ^{4}}{e ^{1.6} \cdot 4 !}

乘以:

1 \cdot 1. 6^{4} = 1. 6^{4}

= \frac{1. 6 ^{4}}{e ^{1.6} \cdot 4 !}

1. 6^{4} = 6.5536

= \frac{6.5536}{e ^{1.6} \cdot 4 !}

e^{1.6} \cdot 4! = 24 e^{1.6}

= \frac{6.5536}{24 e ^{1.6}}

e^{1.6} = 4.95303 \dots

= \frac{6.5536}{24 \cdot 4.95303 \dots}

数字相乘:

24 \cdot 4.95303 \dots = 118.87277 \dots

= \frac{6.5536}{118.87277 \dots}

数字相除:

\frac{6.5536}{118.87277 \dots} = 0.05513 \dots

= 0.05513 \dots
