Deriving the Definition of a Negative Exponent Using
By simplifying the expression using two distinct methods, we can establish the formal definition of a negative exponent. First, applying the Quotient Property for Exponents by subtracting the denominator's exponent from the numerator's exponent yields . Alternatively, we can simplify the expression by expanding it and dividing out the common factors: rewriting it as allows us to cancel two factors of from both the numerator and the denominator. This process leaves three factors of in the denominator, resulting in . Since both procedures simplify the identical starting expression, their final forms must be equal, demonstrating that . This comparison illustrates the general rule that a negative exponent signifies the reciprocal of the base raised to the corresponding positive exponent.
