What does a comma mean in a square root?

We have this problem in my Discrete Math class: "Give the set to which each of the following numbers belong" and one of the numbers is "sqrt 93," what does the comma mean? I guess it could be a typo, but I don't want to just assume that.

I can't post a picture, but it's just square root of 93 with a comma right after (it's a bulleted list and no other numbers have commas)
