Simplifying and Using the Quotient to a Negative Exponent Property
Apply the Quotient to a Negative Exponent Property to simplify two expressions — one with a purely numerical fraction and one with an algebraic fraction that includes a negative sign.
ⓐ : The base is the fraction and the exponent is . Apply the property : take the reciprocal of the fraction and make the exponent positive, giving . Evaluate by squaring both the numerator and denominator: .
ⓑ : The base is and the exponent is . Apply the property: take the reciprocal and change the sign of the exponent, giving . Raise each component to the third power. Because the exponent is odd, the negative sign is preserved: .
Part (a) demonstrates the basic procedure with a numerical fraction. Part (b) extends it to a variable fraction with a negative sign, showing that an odd exponent keeps the result negative after the reciprocal step.
