Basic Concepts:Logarithmic scale: Richter scale (earthquake), Logarithmic scale: pH scale, Logarithmic scale: dB scale,

$\log_b(X \cdot Y) = \log_b X + \log_b Y$

- IntroductionHow and when to use the product rule:

Without using a calculator, evaluate: ${\log_2(16 \cdot 32)}$ - 1.${\log_3 \sqrt{3} + \log_3 \sqrt{27}}$
- 2.Express as a single logarithm:a)$\log_2 6 + \log_2 5$b)$\log_3 100 + \log_6 5\$
