Answer:
2³
Stepbystep 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
