I have a problem about condensing logarithmic expressions with logs AND lns. Is this possible?

ln 5 + 3 ln 3 - log 4

I have a problem about condensing logarithmic expressions with logs AND lns. Is this possible?

ln 5 + 3 ln 3 - log 4 - Jan 13th 2008, 01:52 PMWWTL@WHL
What base are you working in?

That's exactly how the problem appears. I guess just the assumed bases of e and 10.

well In that case...

ln5 + 3ln3 - log4 = ln5 + ln3^3 - ln4

= ln5 + ln9 - ln4 = ln45 -ln4 =

Hopefully someone will correct me if I'm wrong. - Jan 13th 2008, 02:05 PMcolby2152
