Find the distance between the following pairs of points:
(i) `(2, 3,5)`and `(4,3,1)`
(ii) `(3,7, 2)`and `(2,4, 1)`
(iii) `(1, 3, 4)`and `(1, 3,4)`
(iv) `(2, 1, 3)`and `(2,1,3)`.

Text Solution

Verified by Experts

(i) `(2,3,5) & (4,3,1)`
`= sqrt((4-2)^2 + (3-3)^2 + (1-5)^2)`
`= sqrt(4+ 16)`
`= sqrt(20)`
(ii) `(-3,7,2) & (2,4,-1)`
` = sqrt((-3-2)^2 + (7-2)^2 + (2 +1)^2)`
`= sqrt(25+ 25+9)`
`sqrt109`
