Use the properties of logarithms to rewrite each expression in an equivalent form containing a single logarithm.

log (13/5) + log (5/4)

log (13/4)

Step-by-step explanation:

The property of logarithms of interest here is ...

log (a) + log (b) = log (ab)

Using a=13/5 and b=5/4, we find ...

log (13/5) + log (5/4) = log ((13/5) (5/4)) = log (13/4)
