Short Answer
The process of evaluating logarithmic expressions involves understanding their structure and using the property that relates exponential forms to logarithmic values. The evaluated results are: log‚ÄöCc‚ÄöCC‚ÄöCa‚ÄöCe(3) = 1/3, log‚ÄöCc‚ÄöCa‚ÄöCA‚ÄöCe(27) = 3/4, log‚ÄöCc‚ÄöCa‚ÄöCe(27) = 3/2, and log‚ÄöCc‚ÄöCA/‚ÄöCE‚ÄöCe(27) = -3.
Step 1: Understand the Logarithmic Expressions
Begin by recognizing the structure of logarithmic expressions, which express the exponent that a base number must be raised to in order to achieve a given value. This is crucial for evaluating the logs presented. Each expression will follow the form logbase(value).
Step 2: Evaluate Each Logarithm
Evaluate the logarithmic expressions one by one by using the property that states if x = by, then logb(x) = y. Here are the evaluations:
- A. log27(3) = 1/3 because 27(1/3) = 3
- B. log81(27) = 3/4 because 81(3/4) = 27
- C. log9(27) = 3/2 because 9(3/2) = 27
- D. log1/3(27) = -3 because (1/3)(-3) = 27
Step 3: Recap and Use the Results
Finally, summarize the outcomes from your evaluations for clarity and reference. Knowing these values allows you to understand how the logarithmic functions relate to their bases:
- A. log27(3) = 1/3
- B. log81(27) = 3/4
- C. log9(27) = 3/2
- D. log1/3(27) = -3
