Logs with Different Bases
Date: 11/26/97 at 11:39:33 From: kevin Subject: Logs How do you do an addition problem involving logs with different bases?
Date: 11/26/97 at 15:40:18 From: Doctor Rob Subject: Re: Logs Probably by converting them to a single base. The conversion equation is: log_a(x) = log_b(x)*log_a(b) If you know the two bases explicity, the last log above is a constant you can calculate, and then you have replaced a log to the base a with a log to the base b. -Doctor Rob, The Math Forum Check out our web site! http://mathforum.org/dr.math/
