Answer:

log     21  -  log     6 =  log    7/2

      5                 5              5

Step-by-step explanation:

The formula for the log of a quotient a/b is log a - log b.

Thus, log 21 - log 6 = log 21/6, or log 7/2

In your case the logs are to the base 5, so the actual answer would be:

log     21  -  log     6 =  log    7/2

      5                 5              5
