If you have a.log(b)+ c.log(d), is that equal to,

(a+c)log(bd) or (a.c)log(bd) ?

You know that [itex]a \log b=\log b^a[/itex] and you also know that [itex]\log a+\log b=\log ab[/itex]. Try to apply these to your expression, to find the correct results (both the results you listed are incorrect).

So it would be log(b^a . d^c) ?
