Explain to me like I’m 5, how to determine the square root of a random positive number. And I don’t mean common sense like 16=4, I need to understand the logic.

You mean like how to solve it by hand? There are methods but they’re not easy. Back in the day before calculators, people would have used slide rules or tables for this sort of thing.
You can estimate square roots by looking at what square numbers your target number is between. E.g. if I wanted to know the square root of 42, I would observe that it is more than 36 and less than 49, so I know the square root must be between 6 and 7.
