e^{2x-6}=44.7

解答

e^{2 x - 6} = 44.7

x = \frac{ln ( 44.7 ) + 6}{2}

十进制

x = 4.89998 \dots

求解步骤

e^{2 x - 6} = 44.7

使用指数运算法则

2 x - 6 = ln (44.7)

解

2 x - 6 = ln (44.7) : x = \frac{ln ( 44.7 ) + 6}{2}

x = \frac{ln ( 44.7 ) + 6}{2}

n = 2^{\frac{n}{8}}

208 (1.04)^{t} = 279 (1.01)^{t}

15 = A (1 - e^{- k^{2}})

36 = 18 (1 6^{0.0125 x})

1280 = 5 (2^{t})
