13/12

For addition of fractions make the denominators the same, carrying that through to the numerator. Then add the numerators together and the denominator will be what was made the same. Then simplify if needed.

D

Step-by-step explanation:

log7(a) × logb(7)

Using change of base law, let's convert all of them into lg

lg(a)/lg(7) × lg(7)/lg(b)

lg(a)/lg(b)

Again, using change of base law we can convert this into:

logb(a)
