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.

The video begins by presenting a challenging math Olympiad question involving nested square roots [0:00]. The presenter immediately identifies that the innermost value, the square root of 121, is a perfect square. This allows for a simplification: the square root of 121 is 11 [0:10]. The problem then reduces to finding the square root of the quantity 11 minus the square root of 120.
