I usually like watching "How-To" or a live video on how to do a math process. So what is the following problem type called? I know it includes radicals, but it's not just radicals, since you get things way simpler when just Google-ing "radicals."
And yes, the parenthesis does finish after 6, I just forgot to screenshot that far accidentally.
$$\sqrt 3(4-2\sqrt 6)$$
