Hello!

New to mathematica so please bear with me..

When I solve a log[], it convertes it to natural logs. Is there a way to instruct mathematica to keep the original base.

For example:

Log[3,1000]/Log[3,27] should simplify to Log[3,10] but I am getting: Log[10]/Log[3] after simplification.

Then I tried a basic Identity:

Log[b, xy] and I got Log[xy]/Log[b] instead of Log[b,x]+Log[b,y].

What am I missing?
