It isn't clear what you're trying to do, but
log 5 10 = log 5 30 = ?? No, it doesn't.
--------------
ln20 - ln5 =
= log(5/20) = log(4) + ~ 0.60206
---------------
2 log 3 = log 5 - log 15
That's not true, either. ???

Your first problem makes no sense. . So the only answer possible is:

False, meaning the statement "the base 5 log of 10 is equal to the base 5 log of 30" is a false statement.

The difference of the logs is the log of the quotient, so:



Your third problem makes no sense either. How can be equal to ?
