e^{6-4x}=9

解答

e^{6 - 4 x} = 9

x = \frac{- 2 ln ( 3 ) + 6}{4}

十进制

x = 0.95069 \dots

求解步骤

e^{6 - 4 x} = 9

使用指数运算法则

6 - 4 x = ln (9)

解

6 - 4 x = ln (9) : x = \frac{- 2 ln ( 3 ) + 6}{4}

x = \frac{- 2 ln ( 3 ) + 6}{4}

e^{6 - 4 x} = 4

118 = 450 - 390 e^{- \frac{t}{150}}

4^{x - 3} = 64

so l v e f or x, 2^{x} + 1 = 2^{y}

16 = 5 + 16 e^{x (34)}
