As a data analyst for a logistics firm, you need to document a standard operating procedure (SOP) for manually verifying an automated system's base-4 scaling factors. To do this, you must demonstrate how to evaluate the expression $\log_4 64$ without a calculator by relying on exponential conversion. Arrange the steps of this procedural calculation in the correct sequence.

A laboratory technician is tracking the growth of a specific bacterial culture that triples in size every hour. To determine how many hours ($x$) it takes for the culture to increase by a factor of 81, the technician needs to solve the logarithmic equation $\log_3 81 = x$. According to the method of converting to exponential form, which equation correctly represents the first step in solving for $x$?

A technical support specialist is analyzing system growth logs that utilize different logarithmic bases. Match each logarithmic expression with the correct exponential equation that represents the first step in its manual evaluation.

An acoustic engineer is measuring sound attenuation and needs to evaluate the expression $a = \log_2 \left(\frac{1}{8}\right)$. To solve for $a$, the engineer converts the expression to the exponential equation ${}2^a = \frac{1}{8}$. The value of $a$ is ____.

A financial analyst is calculating the order of magnitude for a company's revenue growth using the expression $\log_{10} 1000$. To evaluate this expression manually, the analyst should convert it to the exponential equation ${}10^x = 1000$.
