The video tutorial addresses a challenging math problem involving the simplification of a square root. It begins by breaking down the number four into its factors and manipulating them under the square root. The tutorial then demonstrates how to rewrite numbers to form a perfect square trinomial, which is factored and simplified. Finally, the video compares the decimal forms of the original and simplified expressions to verify the correctness of the solution.
