Hello. I'm working on Logarithms right now. On the problems that I'm working on they have a number in front of LOG. What is it? And how do you go about solving it or entering it into StudyWorks? The problem that I'm on right now is:
Do not become concerned, that 5 in front is just multiplication. It may be more clearly written:
OR, with a logarithm property
Neither of these should pose much problem for entry into StudyWorks.
The Base 12, on the other hand, is a bit trickier, since StudyWorks does not have an arbitrary base placeholder on a logarithm function. All is not lost, however, knowing this principle:
logb(a) = logc(a) / logc(b)
Where 'c' is anything valid (For example, -1 might be a bad choice and zero (0) would be a very bad choice.) c=10 is very popular before calculus. c=e is very popular after calculus.
Using c=10, then: (Recall logwith no base written() is assumed to be base 10)
log12(25) = log(25) / log(12)
5�log12(2) = 5�log(2) / log(12)
Thanks for joining us.
