(5^x)^3*25=1

解答

(5^{x})^{3} \cdot 25 = 1

x = - \frac{2}{3}

十进制

x = - 0.66666 \dots

求解步骤

(5^{x})^{3} \cdot 25 = 1

使用指数运算法则

x \cdot 3 = - 2

解

x \cdot 3 = - 2 : x = - \frac{2}{3}

x = - \frac{2}{3}

8 = 4 e^{10 x}

4^{(x + 4)} - 4^{(x + 3)} = 96

so l v e f or x, 5 e^{2 - x} = 1 0^{x + 4}

12 5^{x - 2} = 25

8 \cdot 3^{x + 1} + 3^{x + 1} = 1
