Question

Choose the single logarithmic expression that is equivalent to the one shown.

Answer 1

log 24. The formula for logarithmic addition is log (a) + log (b) = log(ab). Substituting 8 and 3 for a and b respectively gives the result log 24.

Answer 2

The first thing you should know is that there are properties for logarithms.
 One of them is the following one:
 Let a and b be numbers, by property of logarithms:
 log (a * b) = log (a) + log (b)
 Therefore, by applying the property shown we have:
 log 8 + log 3 = log (8 * 3)
 log 8 + log 3 = log (24)
 the answer is
 log 24
