VERY CORRECT
Note: How do we remember this "change of base" rule?
Decide upon a new base and the given single logarithm is going to be expressed as one logarithm in the nr divided by another logarithm in the denominator with the new base as the base for the numerator logarithm as well as for the denominator logarithm.
