Condense the expression

log5 21 - log5 6

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
