I got stuck on this question because I couldn't remember how to simplify the results, but the only suggested video was the one about the Pythagoras part of the question, which I had no problem with :)
Could I suggest this question also includes a suggestion to watch the video about Square Roots as well, especially if the user has just entered an answer that needs simplifying..
