Answer:
2^3
Step-by-step explanation:
2^-5×2^8=2^(-5+8)
= 2^3
2³
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⁾ ⁺ ⁸
= 2³ Simplified exponent form
= 8 Most simplified form
The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 76 are: 1, 2, 4, 19, 38, 76
Then the greatest common factor is 1.
There are no common factors other than 1
