Answer 1

8.

log 9       log 16       log 9         log 4^2   log 9            2log 4

--------- + --------- = ---------- + ---------- = -----------  + ------------- = 1/2 + 2 = 5/2

log 81      log 4      log 9^2        log 4      2log 9             log 4

 

7.                                      1                           log6 5

a = log3 6 * log6 5 = --------- * log6 5 = ------------ = log3 5

                                      log6 3                     log6 3

 

6.

     1             1

--------- + --------- = logπ 2 + logπ 5 = logπ (2 * 5) = logπ 10

log2 π     log5 π
