Simplifying , , and Using the Negative Exponent Definition
Apply the negative exponent definition to three expressions that combine a coefficient with a variable raised to — contrasting how parentheses determine which part of the expression the exponent acts on, and how a negative coefficient introduces an extra sign step. All variables are assumed nonzero.
ⓐ : Without parentheses, the exponent applies only to the base , not to the coefficient . Apply the negative exponent definition to alone: . The expression becomes .
ⓑ : The parentheses make the entire product the base of the exponent . Apply the negative exponent definition to the whole base: .
ⓒ : The base is now , including the negative sign. Apply the negative exponent definition: . Then apply the Negative Sign Placement in Fractions property to rewrite the result as .
Comparing the three results highlights that parentheses control which quantity the exponent acts on. In part (a), only the variable is reciprocated and the coefficient stays in the numerator. In part (b), the entire product moves to the denominator. In part (c), the negative base produces a negative fraction after the sign is repositioned.
