Question

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

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

Answer 1

log(13/4)

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)
