Logarithms mathematics

This question seems to have multiple asnwers.

  1. X2Y÷X2Y2=1/Y 1/Y÷Y3=1/Y4 → -4lnY
  2. X2Y÷X2/Y–> 2LnY
    The answer is B.

yeah I agree with your first option as well
shouldn’t we do it in order from left to right?

The problem is when you do it in order, the answer wouldn’t be correct based on it’s answer key.

I am unable to get the “correct answer”. If i do reverse equation, it doesn’t work.

By solving it multiple ways, I constantly get -4lny so I would say it’s possible there are mistakes in the book.
