Question

Please help me fast with this, I previously asked 3 question, but I received no answer. ​

Answer 1

Ans will be D since we get 1 on simplification.

Properties used -

log(a)+log(b)=log(ab).

All the terms on multiplication will get cancelled and only the 1st and last term will be left which on further simplification reduce to 1. I also used base change theorm which you must be familiar with.

Hope this helps
