Chapter 4: Problem 106

Describe the quotient rule for logarithms and give an example.

Short Answer

Expert verified
The quotient rule for logarithms states that the logarithm of a quotient of two numbers equals the difference of the logarithms of these two numbers. For instance, \( \log-b(\frac{m}{n}) = \log_b m - \log_b n \). In the example of \( \log_2(8/4) \), using the quotient rule gives the result of 1.

Step by step solution

01

Description of the Quotient Rule

The quotient rule for logarithms states that the logarithm of a quotient of two numbers is the difference of the logarithms of those two numbers. In other words, if you have \( \log_b(\frac{m}{n}) \), it can be written as \( \log_b m - \log_b n \), where b, m, and n are real numbers, and both b and \( \frac{m}{n} \) are greater than zero.
02

Writing the Quotient Rule Formula

The quotient rule of logarithms can be expressed mathematically as follows: \[ \log_b(\frac{m}{n}) = \log_b m - \log_b n \] This is the formal way of expressing the rule.
03

Providing an Example

For example, if you have \( \log_2(8/4) \) (log base 2 of 8 divided by 4). Using the quotient rule, you can express this as \( \log_2 8 - \log_2 4 \). So the calculation would then be: \( 3-2 =1\)

Students in a mathematics class took a final examination. They took equivalent forms of the exam in monthly intervals thereafter. The average score, \(f(t),\) for the group after \(t\) months was modeled by the human memory function \(f(t)=75-10 \log (t+1), \quad\) where \(\quad 0 \leq t \leq 12 . \quad\) Use \(\quad\) a graphing utility to graph the function. Then determine how many months elapsed before the average score fell below 65.

Determine whether each statement makes sense or does not make sense, and explain your reasoning. Because the equations $$\log (3 x+1)=5 \text { and } \log (3 x+1)=\log 5$$ are similar, I solved them using the same method.

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. Examples of exponential equations include \(10^{x}=5.71\) \(e^{x}=0.72,\) and \(x^{10}=5.71\)

Graph \(f\) and \(g\) in the same viewing rectangle. Then describe the relationship of the graph of g to the graph of \(f\). $$f(x)=\log x, g(x)=-\log x$$
