log_{2}((4x+6)^2)=4

解答

lo g_{2} ((4 x + 6)^{2}) = 4

x = - \frac{1}{2}, x = - \frac{5}{2}

十进制

x = - 0.5, x = - 2.5

求解步骤

lo g_{2} ((4 x + 6)^{2}) = 4

使用对数运算法则

(4 x + 6)^{2} = 16

解

(4 x + 6)^{2} = 16 : x = - \frac{1}{2}, x = - \frac{5}{2}

x = - \frac{1}{2}, x = - \frac{5}{2}

0.324 - ln (\frac{T}{303.15}) = 0

lo g_{\frac{3}{5}} (x) = - 3

lo g_{10} (x + 1) + lo g_{10} (2 x) = 2

3 ln (p) + 7 ln (1 - p) = 0

2 lo g_{e} (x) + lo g_{e} (x) = 0
