Algebra II: Convert logarithmic expression from one base to another
 This is a free lesson from our course in Algebra II

 In this section you'll look at a property of logs that they let you change bases by simple division. E.g. logbx = logax / log ab. This can be done with Natural logs as well, using the following equation: logbx = ln(x) / ln(b). For example, the logarithmic expression log21024 to base 16 can be written as log161024 log216.Properties of logarithm: loga(xy) = logax + logay loga(x/y) = logax - logay (More text below video...)

(Continued from above) loga(xr) = r logax
logaa = 1
loga1 = 0
loga(1/ x) = -loga x
logax = log x / log a = ln x / ln a
