A technician is reviewing a formula that includes the term $\left(\frac{x}{y}\right)^{-3}$. To simplify this part of the formula using only positive exponents, which of the following expressions should they use?

A quality control inspector is simplifying a defect-to-production ratio formula: $\left(\frac{a}{b}\right)^{-5}$. Arrange the following steps in the correct order to rewrite this expression using only positive exponents.

A laboratory technician is simplifying a chemical concentration ratio represented by the expression $\left(\frac{c}{v}\right)^{-8}$. True or False: The simplified version of this expression using only positive exponents is $\frac{v^8}{c^8}$.

In a quality control department, technicians use various ratios to monitor equipment performance. Match each original performance ratio with its correctly simplified version using only positive exponents.

A data analyst is auditing a legacy formula that contains the expression $\left(\frac{m}{n}\right)^{-7}$. To rewrite this expression using only positive exponents, the analyst first distributes the exponent to get $\frac{m^{-7}}{n^{-7}}$. By applying the definition of a negative exponent, the term $n^{-7}$ is moved to the ____ to become $n^7$.
