Question #24816

Answer 1

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.
