Use Log Relationship: Use the relationship between the logs of prime numbers to find the value of $\log 5$ . We know that $\log(ab) = \log a + \log b$ . Since $10$ is the product of $2$ and $5$ , we can write $\log 10$ as $\log(2 \times 5)$ which is equal to $\log 2 + \log 5$ . We also know that $\log 10 = 1$ . So, $\log 2 + \log 5 = 1$ .
Substitute Log $2$ : Substitute the given value of log $2$ into the equation. $\newline$ $\log 2 + \log 5 = 1$ $\newline$ $0.3010 + \log 5 = 1$
Solve for $\log 5$ : Solve for $\log 5$ . $\log 5 = 1 - 0.3010$ $\log 5 = 0.6990$

A biologist puts a certain number of DNA strands into a machine, which uses a process called PCR cycling. Each PCR cycle, the machine creates a copy of every DNA strand. All of the DNA strands (the original DNA strands and their copies) remain together in the machine, ready for more PCR cycles. If a biologist puts

1

thousand DNA strands into the machine and runs it for

4

cycles, how many DNA strands will be in the machine at the end of the process, in thousands?
