There is no logarithm base provided in the expression "log 5 + 2". Therefore, we assume that the base is 10, which is the default base for logarithms when no base is specified.
Using the logarithmic identity that states
"log a + log b = log(ab)",
we can combine the terms as follows:
log 5 + 2 = log(5) + log(10^2) [Note that 10^2 = 100]
Now, using the same identity, we can simplify this further:
log(5) + log(100) = log(5 * 100) = log(500)
Therefore, the expression "log 5 + 2" can be simplified as a single logarithm of "log 500" with base 10.
