How Will This Worksheet on "Condense Logarithms Using the Product Property" Benefit Your Student's Learning?

  • Combining logarithms using the product property simplifies complex math problems by consolidating terms.
  • Adding logarithms into one expression makes calculations quicker and easier.
  • Understanding how to condense logarithms helps students handle more challenging math problems effectively.
  • Prepares students for advanced math topics like calculus and algebra by building a strong foundation.
  • Reduces the chance of errors in calculations, ensuring accuracy.

How to Condense Logarithms Using the Product Property?

  • Begin with separate logarithmic terms, such as \(\log_b(x)\) and \(\log_b(y)\).
  • Combine the separate logarithms using the product property, which states \(\log_b(x) + \log_b(y) = \log_b(xy)\), ensuring the bases are the same.
  • Multiply the arguments inside the logarithm to condense the expression into a single logarithm of their product.
  • Ensure that the condensed logarithm accurately represents the original separate logarithmic terms combined into a single expression.

Solved Example

Q. Condense the logarithm. Assume all expressions exist and are well-defined.\newlineloga5+loga3\log_a 5 + \log_a 3
Solution:
  1. Identify Property: Identify the property of logarithm used to condense loga5+loga3\log_a 5 + \log_a 3.\newlineSince these logarithms have the same base, we can apply the product rule to condense the logarithms:
  2. Apply Sum Property: Apply the product property to condense loga5+loga3\log_a 5 + \log_a 3.\newline logbP+logbQ=logb(PQ)\log_b P + \log_b Q = \log_b (PQ)\newlineloga5+loga3=loga(53)\log_a 5 + \log_a 3 = \log_a (5 \cdot 3)
  3. Simplify Expression: Simplify the expression inside the logarithm.\newlineloga(53)=loga15\log_a (5 \cdot 3) = \log_a 15

Condensing logarithms using the product property involves combining addition logarithmic terms into a single logarithm of a product. For instance, \(\log_b(x) + \log_b(y)\) condenses to \(\log_b(xy)\) when the bases are the same. This method simplifies complex logarithmic expressions by reducing them into more compact and manageable forms, which is useful for calculations and problem-solving in various mathematical contexts.
Example: Condense the logarithms \(\log_2(3) + \log_2(5)\) using the product property.
