Oh, a math Olympiad question! These always look intimidating at first glance, but I bet there's a neat trick involved. The presenter jumping right into simplifying the inner square root is a good sign.
Yep, they found the square root of 121 is 11! That immediately makes the problem so much more manageable. Going from a nested square root to just '11 minus the square root of 120' is a huge step.
The presenter is already thinking about how to rewrite that '11 - sqrt(120)' expression. This is where the algebraic magic usually happens in these types of problems.
