A technician is adjusting a measurement on a blueprint using a scaling factor of $\left(\frac{2}{3}\right)^{-4}$. Which of the following expressions is equivalent to this factor and represents the correct first step in simplifying it?

A design engineer is simplifying a scaling ratio $\left(-\frac{m}{n}\right)^{-2}$ for a machine part. To reach the final simplified form using the Quotient to a Negative Exponent Property, arrange the following steps in the correct order.

A logistics analyst uses the expression $\left(-\frac{m}{n}\right)^{-2}$ to model a change in shipping efficiency. True or False: To rewrite this expression with a positive exponent, the analyst should first use the reciprocal of the fraction, resulting in $\left(-\frac{n}{m}\right)^2$.

A manufacturing engineer is reviewing scaling ratios used to adjust dimensions for a precision-engineered bracket. Match each scaling expression with its correctly simplified form using the appropriate property for negative exponents.

A quality assurance technician is calculating error bounds using a formula that includes the scaling factor $\left(-\frac{m}{n}\right)^{-2}$. To begin simplifying this term and rewrite it with a positive exponent, the technician must apply the property that requires taking the ________ of the base fraction.
