The given expression will be equal to Zero

#5,9,13,.....# this is in AP having first term 5 and common difference 4.

Let 45 be its nth term.

So #5+(n-1)*4=45#

#=>n-1=(45-5)/4=10#

#=>n=10+1=11#

So 11 th term of the AP is 45.

Hence 11 th factor of the given product will be

#logtan45=log1=0#

So value of the given expression will be Zero.
