Just like the explanation shows the answer should be 3x^−2, not 3x^2. I don't see any ^-x at all actually, so it might have to do with my screen. It's also very difficult to see the difference between ^2 and ^3 (And my vision is fine, thank you for wondering :P). There was a similar problem in another question as well. Maybe you could make the answers a size bigger and then it will show up? Think you guys are doing an awesome job btw. Although I wish more people with spanish skills would contribute with subtitles.
