Cyosis Homework Helper Messages 1,495 Reaction score 5 Jun 11, 2009 #2 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). Last edited: Jun 11, 2009
