As an engineering technician, you are programming a mathematical modeling tool to simplify complex formulas for material stress, such as converting the expression $\sqrt[4]{80x^7y^4}$ into ${}2|xy|\sqrt[4]{5x^3}$. You are configuring the software's rules for when to include absolute value signs. Based on the properties of roots, under what specific condition must your program apply absolute value signs around a variable that has been extracted from a radical?

As a technical quality reviewer for an educational software project, you are auditing a lesson on simplifying radicals. To ensure the content is accurate, match each radicand component from the expressions $\sqrt{180m^9n^{11}}$, $\sqrt[3]{72x^6y^5}$, and $\sqrt[4]{80x^7y^4}$ with its corresponding largest perfect power factor that must be factored out based on the index of the root.

In a technical training module for industrial design, you are asked to simplify the radical expression $\sqrt[3]{72x^6y^5}$. True or False: Absolute value signs are required around the variable $y$ in the final result because it is extracted from the radical with an odd power.

As a quality control reviewer for an industrial training module, you are auditing a guide on simplifying mathematical formulas used in material stress analysis. Arrange the following steps in the correct order to simplify the radical expression $\sqrt{180m^9n^{11}}$ using the Product Property of Roots.

While updating the company's technical reference manual for mathematical algorithm development, you document the rules for simplifying radical expressions like $\sqrt{180m^9n^{11}}$ and $\sqrt[4]{80x^7y^4}$. According to the properties of roots, when extracting variables from a root with an even index, you must place absolute value signs around the extracted variable if its resulting power is ____.
