Question

What is the distance between `(8, 6, 2)` and # (4, 3, 1) #?

Answer 1

`sqrt (26)`

Explanation:

Using the distance formula for 3-D space viz

`d = sqrt ((x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2)`

Where

`(x_1, y_1, z_1)` = (8, 6, 2)

`(x_2, y_2, z_2)` = (4, 3, 1)

Substitute in distance formula
