In this section you'll look at a property of logs that they let you change bases
by simple division. E.g. log_{b}x = log_{a}x /
log _{a}b. This can be done with Natural logs as well, using the
following equation: log_{b}x = ln(x) / ln(b).
For example, the
logarithmic expression log_{2}1024 to base 16 can be
written as log_{16}1024 log_{2}16. Properties of logarithm:
log_{a}(xy) = log_{a}x + log_{a}y
log_{a}(x/y) = log_{a}x  log_{a}y(More text below video...)
(Continued from above)
log_{a}(x^{r}) = r log_{a}x
log_{a}a = 1
log_{a}1 = 0
log_{a}(1/ x) = log_{a}x
log_{a}x = log x /
log a = ln x / ln a
