About This Worksheet

This medium-level worksheet contains 24 problems designed for 11th Grade students practicing properties of logarithms. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.

Logarithm properties are the algebraic tools that make solving exponential and logarithmic equations tractable. They appear throughout higher mathematics — in information theory, physics, and calculus — and developing fluency with them pays dividends across every quantitative field.

  • Apply the Product Rule, Quotient Rule, and Power Rule for logarithms
  • Expand and condense logarithmic expressions using the three properties
  • Use the Change of Base Formula to evaluate logarithms with any base on a calculator
  • Simplify expressions involving log and ln by applying multiple properties in sequence
  • Rewrite exponential equations in logarithmic form before applying properties
