Chapter 4: Problem 139

Determine whether each statement makes sense or does not make sense, and explain your reasoning. I can solve \(4^{x}=15\) by writing the equation in logarithmic form.

Short Answer

Expert verified
The statement makes sense. The exponential equation \(4^{x} = 15\) can indeed be written, and thus solved, in its equivalent logarithmic form as \(\log_{4}(15) = x\).

Step by step solution

01

Understanding the Exponential and Logarithmic form

An equation is in exponential form if it is written as '\(b^{a} = c\)', where \(b\) is the base, \(a\) is the exponent and \(c\) is the result. It can be converted into logarithmic form: \(\log_{b}(c) = a\). These two are equivalent.
02

Converting the given equation into Logarithmic Form

The given equation is \(4^{x}=15\). Convert that into logarithmic form gives, \(\log_{4}(15) = x\).
03

Explanation of the Conversion

In the transformation, the base of the exponent becomes the base of the logarithm (\(4\) in this case), the result or output of the exponential expression is the input or argument of the logarithmic function (which is \(15\)), and the exponents are identical in both forms (\(x\) in this case).

Evaluate or simplify each expression without using a calculator. $$ \log 100 $$

In Exercises \(121-124\), determine whether each statement makes sense or does not make sense, and explain your reasoning. I expanded \(\log _{4} \sqrt{\frac{x}{y}}\) by writing the radical using a rational exponent and then applying the quotient rule, obtaining \(\frac{1}{2} \log _{4} x-\log _{4} y\)

Determine whether each statement makes sense or does not make sense, and explain your reasoning. Because the equations \(2^{x}=15\) and \(2^{x}=16\) are similar, \(I\) solved them using the same method.

Evaluate or simplify each expression without using a calculator. $$ \ln e^{9 x} $$

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 \(f(t)=75-10 \log (t+1),\) where \(0 \leq t \leq 12\). Use a graphing utility to graph the function. Then determine how many months elapsed before the average score fell below 65.
