e^{6x}=13

解答

e^{6 x} = 13

x = \frac{ln ( 13 )}{6}

十进制

x = 0.42749 \dots

求解步骤

e^{6 x} = 13

使用指数运算法则

6 x = ln (13)

解

6 x = ln (13) : x = \frac{ln ( 13 )}{6}

x = \frac{ln ( 13 )}{6}

so l v e f or x, h = a^{- x}

3^{2 x + 3} = 2 7^{4 x - 4}

e^{x} + e^{2} x = e^{3} x

4^{x + 1} - 5^{x + 1} = (0.8) (4^{x})

1.73 = 3^{x}
