One of the rules of logarithms is as follows;

\begin{gathered} \log _ab=x \\ Is\text{ equivalent to,} \\ a^x=b \end{gathered}

We can now insert the corresponding values in the question provided, as shown below;

\begin{gathered} \log _2\frac{1}{16}=-4 \\ \text{This is equivalent to,} \\ 2^{-4}=\frac{1}{16} \end{gathered}

Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;

a^{-x}=\frac{1}{a^x}

Therefore, our equation can now be re-written as follows;

\begin{gathered} 2^{-4}=\frac{1}{16} \\ \frac{1}{2^4}=\frac{1}{16}^{} \\ \frac{1}{16}=\frac{1}{16} \end{gathered}

However, the question requires the answer to be expressed in exponential form. Therefore,

\log _2\frac{1}{16}=2^{-4}

Ten vendors are selling at an event, and an attendance of 42,000 is projected. It is anticipated that 65 percent of the attendee
In-s [12.5K]
For this case, the first thing we must do is calculate the number of attendees who will make purchases.
 We have then:
 (42000) * (0.65) = 27300
 We are now looking for the number of attendees that each vendor will attend.
 We have then:
 N = (27300) / (10)
 N = 2730
 Answer:
 
the average number of customers each will serve is:
 
N = 2730
