Pay attention to how they simplify expressions before solving—this is the "trick" to the Nikolaev advanced problems.
The textbook is excellent for developing logical rigor. If you are using GDZ with it:
Because the Nikolaev/Mordkovich problems are more complex than the standard version, GDZ can act as a "tutor" by showing the logical steps for difficult proofs and multi-step equations.
