Condensing Logarithmic Expressions
The opposite of expanding a logarithm is to condense a sum or difference of logarithms that share the same base into a single logarithmic expression. This process involves using the properties of logarithms in reverse. To condense these expressions, first apply the Power Property, , to move any coefficients back as exponents, ensuring all log terms have a coefficient of one. Once the coefficients are resolved, use the Product Property and Quotient Property as needed to combine the terms into a single logarithm.
