0.567=ln(x^2)

解答

0.567 = ln (x^{2})

x = e^{0.567}, x = - e^{0.567}

十进制

x = 1.32776 \dots, x = - 1.32776 \dots

求解步骤

0.567 = ln (x^{2})

使用对数运算法则

e^{0.567} = x^{2}

解

e^{0.567} = x^{2} : x = e^{0.567}, x = - e^{0.567}

x = e^{0.567}, x = - e^{0.567}

2 lo g_{3} (x) - 1 = lo g_{3} (2 x - 3)

ln (x) + ln (x - 3) = ln (7 x)

lo g_{3} (x + 2) + lo g_{3} (x - 4) = 3

(ln (x - 1)) (ln (x - 1) - 2) = - 1

lo g_{10} (3 x) + lo g_{10} (5) = 1
