Why do we use square roots and squares in the distance formula Wholdnt they cancel each other out?
Please reply quick PLEASE


Hi Joe,

Try it yourself: Put a dot on a sheet of paper, and a second dot 3 cm below and 4 cm to the left of it. Then measure the distance between the two dots with a ruler.

Is it sqrt(32 + 42) = sqrt(9 + 16) = sqrt(25) = 5 cm, or 3 + 4 = 7 cm?
