320000=250342e^{0.012x}

解答

320000 = 250342 e^{0.012 x}

解答

x = \frac{ln ( \frac{160000}{125171} )}{0.012}

+1

十进制

x = 20.45775 \dots

求解步骤

320000 = 250342 e^{0.012 x}

交换两边

250342 e^{0.012 x} = 320000

两边除以

250342

e^{0.012 x} = \frac{160000}{125171}

使用指数运算法则

0.012 x = ln (\frac{160000}{125171})

解

0.012 x = ln (\frac{160000}{125171}) : x = \frac{ln ( \frac{160000}{125171} )}{0.012}

x = \frac{ln ( \frac{160000}{125171} )}{0.012}
