Understanding Integer Properties and Constraints

The video tutorial explores a mathematical problem involving two positive integers that differ by 60. The sum of their square roots equals the square root of a non-perfect square integer. The goal is to find the maximum possible sum of these integers. The instructor breaks down the problem, derives necessary equations, and tests various factors of 900 to find the solution. The maximum sum is determined to be 156, with integers 108 and 48 meeting all conditions.
