Evaluate expression using change of base
This is an awkward question to me, it was not covered in class.
Suppose:
logb2=A
logb3=B,
logb5=C
Then, use the change-of-base formula to evaluate
logb25
and
logb2.
As an example answer, we're given log3b becomes 1B
Hopefully someone understands where they're coming from.

logxy=lnylnx
So,
logb25=ln5lnb2=ln52lnb
and you should be able to continue from here.
Edit: I just realized that you may not know what ln is. In which case think of it as loge where e is a well known number e=2.71828
