Kind of an offshoot of my previous post but this has to do with logarithmic properties

Change of base:

logbX = logaX/logaB

and

logb(X/Y ) = logbX - logbY

and

X/Y = X(1/Y) exponents


here is the formula I have:
logc (b / a) where c = 3, b = 88 , a = 3

how can I write b/a: Is it actually

logc (logcb - logxa) or

logc (X(1/Y)

confused on how to proceed with the b/c- do I simpify that first then convert from base 5 to base 10

Insight would be appreciated...
