Final answer:
The sum log5(3) + log5(8) can be expressed as log5(24).
Step-by-step explanation:
The sum of logarithms with the same base can be expressed as the logarithm of the product of the numbers inside the parentheses.
Using this property, the given expression can be rewritten as log5(3 x 8).
Therefore, the sum log5(3) + log5(8) can be expressed as log5(24).
