You are a logistics planner completing a technical certification on predictive supply chain models. The certification requires you to evaluate three algorithmic constraints formulated as logarithmic equations: Model A is $\log_x 81 = 2$, Model B is $\log_3 x = 5$, and Model C is $\log_{\frac{1}{3}} \frac{1}{27} = x$. To find the unknown variable $x$ in each model, you must recall how to convert logarithmic equations to their exponential form and apply the rules for logarithmic bases. Which of the following correctly identifies the equivalent exponential form and final valid solution for one of these models?

A technician is calibrating three different sensor systems where the signal attenuation is modeled by logarithmic equations. Match each logarithmic equation to its equivalent exponential form required for solving.

A quality control analyst is using the logarithmic model $\log_x 81 = 2$ to determine a system's scaling factor $x$. Arrange the following steps in the correct order to solve for the valid value of $x$ according to the standard procedure for converting logarithmic equations.

A marketing analyst is using the logarithmic equation $\log_x 81 = 2$ to determine a brand's reach factor $x$. After converting the equation to its exponential form $x^2 = 81$, the analyst determines that $x = 9$ is the only valid solution because the base of a logarithm must always be a positive number.
