    • What are negative exponents?

    Negative exponents tell us that the power of a number is negative and it applies to the reciprocal of the number. We know that an exponent refers to the number of times a number is multiplied by itself. For example, 3 2 = 3 × 3.

    What is a negative exponent?

    Negative exponents. A negative exponent is equal to the reciprocal of the base of the negative exponent raised to the positive power. This is expressed as. where b is the base, and n is the power. In other words, a negative exponent indicates the inverse operation from a positive integer exponent: it indicates how many times to divide by the base, rather than multiply.

    How can you evaluate negative exponents?

    3 raised to the power of 4 is written 3 4 = 81.

  • -4 raised to the power of 2 is written (-4) 2 = 16.
  • -3 raised to the power of 3 is written (-3) 3 = -27.
  • For 0 raised to the 0 power the answer is 1 however this is considered a definition and not an actual calculation.

    • How to get rid negative exponents?

    Negative Exponents. Consider the Division Law with a = 0. But remember: x0 = 1.

  • Fractional Exponents. How can we define fractional exponents so that the Laws of Exponents remain consistent? Consider any fraction,say 1/2.
  • Practice Problems. Now are you ready for some practice? For each problem below,simplify as much as possible.

    • How to factor trinomials with negative exponents?

    Completely factor all numerators and denominators.

  • Reduce all common factors.
  • Either multiply the denominators and numerators or leave the answer in factored form.
