In technical applications, such as calculating material tolerances, you may encounter expressions like {}27^{-rac{2}{3}}. Arrange the following steps in the correct order to simplify this expression to its final numerical form.

As an inventory analyst, you calculate depreciation factors for industrial machinery. The formula uses negative rational exponents to model the decline in value over time. Match each raw depreciation factor expression to its correctly simplified fractional value to ensure accurate financial reporting.

In a construction project, a blueprint scaling factor is represented by the expression ${}81^{-\frac{3}{2}}$. Which of the following simplified fractions represents this factor?

In a technical manual for industrial materials, a stress-tolerance factor is represented by the expression ${}625^{-\frac{3}{4}}$. To simplify this for calculation, the factor is rewritten as $\frac{1}{625^{\frac{3}{4}}}$ and then expressed in the radical form $\frac{1}{(\sqrt[4]{625})^3}$. Recalling the final evaluation of this specific expression, the simplified numerical fraction for this factor is ____.

In a quality assurance report for high-precision components, an engineer defines a calibration adjustment factor using the expression ${}16^{-\frac{3}{4}}$. True or False: The simplified numerical value of this factor is $\frac{1}{8}$.
