Condensing logarithms involves using the properties of logarithms to rewrite an expression with multiple logarithmic terms into a single logarithmic term. The key properties include the product rule, quotient rule, and power rule. By applying these rules, you can combine sums and differences of logarithms into a single, more concise expression. This skill is essential for solving logarithmic equations and simplifying complex mathematical expressions.
Match the term with its definition:
| Term | Definition |
|---|---|
| 1. Power Rule | A. $\log_b(x) - \log_b(y) = \log_b(\frac{x}{y})$ |
| 2. Product Rule | B. $\log_b(x \cdot y) = \log_b(x) + \log_b(y)$ |
| 3. Quotient Rule | C. An exponent to which a base must be raised to produce that number. |
| 4. Logarithm | D. $\log_b(x^p) = p \cdot \log_b(x)$ |
| 5. Condense | E. To reduce to a shorter or more compact form. |
Fill in the blanks with the correct terms to complete the sentences.
