Question

What is the distance between `(-8,8,-1)` and `(3,1,2)`?

Answer 1

The distance is `sqrt179`

Explanation:

Either you do it using vectors or the distance betwwen two points.
If you have two points `(x_1,y_1,z_1)` and `(x_2,y_2,z_2)`

The distance is `=sqrt((x_2-x_1)^2+(y_1-y_2)^2+(z_1-z_2)^2)`
The distance is `=sqrt(11^2+7^2+3^2)=sqrt(121+49+9)=sqrt179`
