8.1^{4x+3}=1

解答

8. 1^{4 x + 3} = 1

x = - \frac{3}{4}

十进制表示法

x = - 0.75

求解步骤

8. 1^{4 x + 3} = 1

使用指数运算法则

(4 x + 3) ln (8.1) = ln (1)

解

(4 x + 3) ln (8.1) = ln (1) : x = - \frac{3}{4}

x = - \frac{3}{4}

4^{x - 6} = 64

2^{5 x + 1} + 2^{5 x + 5} = 17

e^{x} = - 2 x

y^{y^{5}} = 100

x, 2^{x} - 2^{y} = 1
