During a data analysis training session, your instructor emphasizes the importance of correctly formatting formulas in your spreadsheets. To demonstrate, she asks you to evaluate an expression where a negative sign precedes a base with an exponent, without using parentheses. What is the correct value of the expression $-9^2$?

In a corporate training module on spreadsheet accuracy, the instructor explains that for the mathematical expression $-9^2$, the base of the exponent is 9. True or False?

During a quality assurance audit of a company's financial spreadsheet, you are tasked with verifying that formulas involving exponents are producing the intended results. Match each mathematical expression to the description of its simplified value based on the order of operations.

Identifying Bases in Exponential Expressions

A quality control technician is using a spreadsheet to calculate the variance of measurement errors. One part of the formula involves squaring a negative reading, written as ${}(-9)^2$. Arrange the following steps in the correct order to simplify this expression according to the standard mathematical rules for parentheses and exponents.
