$$\log_b (xy) = \log_b x + \log_b y$$

$$\log_b (x+y) = \log_b x + \log_b y$$

$$\log_b (xy) = \log_b x \cdot \log_b y$$

$$\log_b (x/y) = \log_b x + \log_b y$$

$$x = 10$$

$$x = 25$$

$$x = 32$$

$$x = 16$$

$$\frac{\log_{10} 8}{\log_{10} 2}$$

$$\frac{\log_{10} 2}{\log_{10} 8}$$

$$\log_{10} 8 \cdot \log_{10} 2$$

$$\log_{10} (8 \cdot 2)$$

$$\log_b (x^k) = k \log_b x$$

$$\log_b (x^k) = \log_b x + k$$

$$\log_b (x^k) = \log_b (x \cdot k)$$

$$\log_b (x^k) = \frac{\log_b x}{k}$$

$$x = 6$$

$$x = 25$$

$$x = 26$$

$$x = 10$$

$$\log_b \left(\frac{x}{y}\right) = \log_b x - \log_b y$$

$$\log_b \left(\frac{x}{y}\right) = \log_b x + \log_b y$$

$$\log_b \left(\frac{x}{y}\right) = \frac{\log_b x}{\log_b y}$$

$$\log_b \left(\frac{x}{y}\right) = \log_b y - \log_b x$$
