$$ \begin{aligned} & y = \log_a x \ \Longleftrightarrow \ x = a^y \\ \\ \\ & \log x = \log_{10} x \\ \\ & \ln x = \log_e x \\ \\ & e \doteq 2,72 \end{aligned} $$
$$ \begin{aligned} & \log_a x = \frac{\log_b x}{\log_b a} = \frac{\log x}{\log a} = \frac{\ln x}{\ln a} \\ \\ & \log_a x = \frac{1}{\log_x a} \\ \\ & \log_a \left(x \cdot z\right) = \log_a x + \log_a z \\ \\ & \log_a \left(\frac{x}{z}\right) = \log_a x - \log_a z \end{aligned} $$
$$ \begin{aligned} & \log_a x^r = r \cdot \log_a x \\ \\ & \log_a a^r = r \\ \\ & a^{\log_a x} = \log_a a^x = x \end{aligned} $$
$$ \begin{aligned} & \log_a 1 = 0 \\ \\ & \log_a a = 1 \\ \\ \end{aligned} $$
