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(3^{2} + 4^{2}) = sqrt(9 + 16) = sqrt(25) = 5 cm, or 3 + 4 = 7 cm? Claude
