Find the distance of the point `(6,-6)` from the origin

1.	Find the distance of the point `(6,-6)` from the origin
Answer» Let P(6, -6) be the given point and O(0, 0) be the origin. Then, `OP = sqrt((6-0)^(2) + (-6-0)^(2)) = sqrt(6^(2) + (-6)^(2))` ` = sqrt(36+36) = sqrt(72) = sqrt(36 xx 2) = 6sqrt(2)` units.
