I'm so confused on distance formula, I know how to calculate it, but getting the final simplified answer is so confusing. Like so on some equations the final answer is just a regular whole number, others is a number with a square root like 3 -/2, or a number square rooted -/3 it's really confusing for me please help and excuse my squart root symbol (-/) I'm confused when I try to simplify if it's just a regular whole number or a number square rooted or what?
I guess what I'm asking is what are the rules of simplifying the final answer in distance formula after you got the main answer
