A telecommunications engineer is documenting signal attenuation in a network using the algebraic expression $x^{-5}$, where $x$ represents the distance from the transmitter. According to the definition of negative exponents, which of the following is equivalent to this expression?

A laboratory technician is recording measurements for microscopic components. The specifications are currently written using negative exponents, but the database requires them to be entered as simplified fractions. Match each negative exponent expression to its equivalent simplified fraction.

A quality control analyst is reviewing a technical report that contains the expressions $x^{-5}$ and ${}10^{-3}$. True or False: According to the negative exponent definition, the negative sign in these exponents indicates that the simplified results of these expressions are negative numbers.

Data Entry for Laboratory Measurements

An environmental scientist is recording the concentration of a pollutant in a water sample as ${}10^{-3}$ grams per liter. Arrange the steps in the correct order to simplify the expression ${}10^{-3}$ using the definition of negative exponents.
