What conditions must $a$ and $b$ satisfy for the equation to have at least one real solution? Find all the solutions of this equation: $1+\log_b(2\log(a)-x)\log_x(b)=2\log_b(x)$
I have tried restricting the domain of $2\log(a)-x>0$.
$1 + \log_b(2 \cdot \log(a) - x) \cdot \log_x b = \frac{2}{\log_b x}$
$1 + \log_b(2 \cdot \log(a) - x) \cdot \frac{1}{\log_b x} = \frac{2}{\log_b x}$
$log_b x + \log_b (\log(a^2) - \log(10^x)) = 2$
$log_b \left(x \cdot \log\left(\frac{a^2}{10^x}\right)\right) = 2$
$b^2 = x \cdot \log\left(\frac{a^2}{10^x}\right)$
$\frac{b^2}{x} = \log\left(\frac{a^2}{10^x}\right)$
$10^{\frac{b^2}{x}} = \frac{a^2}{10^x}$
Then what should I do? I've tried a lot, that's the reason i ask for help ,isn't because i want some of you to do my "homework" it's because i'm done.
