Logarithmic Properties and Evaluations

The video tutorial explains how to evaluate given logarithms by expanding them using properties such as the quotient, product, and power properties. It provides two examples where the logarithms are expanded and evaluated using substitution based on given values. The first example involves expanding a quotient of logs, while the second example focuses on expanding a product of logs. The tutorial emphasizes careful application of logarithmic properties and substitution to arrive at the final evaluated expressions.

What is the first step in evaluating the given logarithms?

• Ignoring the given values

• Using the power property immediately

• Expanding the logarithms as much as possible

• Performing substitution directly

In the first example, how is a quotient of logs expressed?

• As a power of two logs

• As a difference of two logs

• As a product of two logs

• As a sum of two logs

What property is used to expand a product of logs?

• Power property

• Product property

• Quotient property

• Substitution property

How do you handle the subtraction of expanded logs?

• Subtract the expansion of the logs

• Add the logs

• Multiply the logs

• Divide the logs
