Sir/Mam, I just wanted to know if we can change the order in the distance formula even in the board exam??? i.e. in the formula does it matter if v subtract x2 from x1 or x1 from x2??Is there any risk of losing my marks if I do dis????

Expert Answer:

Distance is a positive quantity and it cannot be negative.
Under the square root the quantity should also be positive.
Since square of any number is a positive quantity, the terms are always positive.
Therefore, the order does not matter even if you change the order.
In board exam they will not reduce any marks for that.
All the best!
