    = 2^3

  • Answer:

    Step-by-step explanation:

    Written in numerical form:

    2⁻⁵ · 2⁸

    Since both exponents have the same base, one of the exponent rules apply. When multiplying exponents with the same base, you add the exponents.

    xᵃ · xᵇ = xᵃ⁺ᵇ

    2⁻⁵ · 2⁸

    = 2⁽⁻⁵⁾ ⁺ ⁸

    = 2³   Simplified exponent form

    = 8    Most simplified form
