Logarithm Tarsia Puzzle Activity

I used this logarithm tarsia puzzle (also know as a square puzzle) with my Algebra 2 students. We glued our finished results in our Algebra 2 interactive notebooks.

I originally found the file for this logarithm puzzle online, but it seems like it has been taken down. I am uploading it below. If this is your resource, please let me know so I can give you credit for the awesome puzzle!
