The sum of the series` log_ab + log _(a^2)b^2+log_(a^3)b^3+....log_(a^n)b^n`

The sequence log a, log a^2/b , log a^3/b^2 , ..... is

Find the sum of n terms of the series log a+log((a^(2))/(b))+log((a^(3))/(b^(2)))+log((a^(4))/(b^(3)))

The sum of the series log_(9)3+log_(27)3-log_(81)3+log_(243)3- ....... is a) 1-log_(e)2 b) 1+log_(e)2 c) log_(e)2 d) log_(e)3

The value of log_(b)a+log_(b^(2))a^(2) + log_(b^(3))a^(3) + ... + log_(b^(n))a^(n)

The sequence log a, log (a^(2)/b), log (a^(3)/b^(2)) is:
