A technical documentation specialist is outlining the logic for a spreadsheet's error-detection module. Arrange the following steps in the correct order to determine if the expression $\sqrt{-169}$ is a real number, based on the standard rules for radicals.

Technical Documentation for Radical Expression Validation

A data analyst is configuring an error-detection script for a financial calculation engine. While the expression $-\sqrt{64}$ is correctly identified as a real number (simplifying to -8), the expression $\sqrt{-169}$ must be categorized as a(n) '____ Number' because there is no real number that results in a negative value when squared.

A technical support representative is assisting a client whose financial spreadsheet returns a 'Non-Real Result' error for the expression $\sqrt{-169}$. Which mathematical principle should the representative recall to explain why this specific expression is not a real number?

A software developer is writing a program to categorize numerical outputs for a technical application. True or False: The expression -$\sqrt{64}$ is considered a real number because the negative sign is located outside the radical.
