Mathematical puzzle from Moscow school mathematical olympiad (2018 and 2021). To solve this math problem one should recall the knoledge about logarithm base (logarithm chain) rules and polynomial factorization. For instance, one should now how to expand (x-a)(x-b)(x-c). However, one should not memorize neither logarithm base change (logarithm switch) rule, nor
(x-a)(x-b)(x-c) formula and can derive them by applying the definition of logartihmic function and guesses about polynomial factoring.

At the end, another mathematical olympiad question from Russian school math olympiad is given for the further discussion.
