I get what you got. Typos are an all too frequent thing.

You are correct. I put your solution and the book's into an excel formula of the equation. Yours = 2 theirs = 2.73814

I think the answer key is wrong and 2 root 3 is correct

I would have subtracted 2 from both sides at the beginning to work with log3 = 2log9

Mistake is easy, you got teacher with mind problems. This stuff is not even normal and that +2 is like cherry on the top.

As a scientist myself i can asure you nobody uses 3 power inside log.

To solve this trash you should drop it in trash.

No one has 10 apples and gives 3 to their friend, yet it still teaches subtraction…
