However, it is NOT ALLOWED to have a logarithm of a negative number or a logarithm of zero, 0 0, when substituted or evaluated into the original logarithm equation. (division rule) It is tempting to try to contract the remaining two logarithms, but read the division rule very closely. It allows us to do something with division within a log", not log divided by log". There is no rule to handle this situation, so we simply leave it as it is.
