What is the distance between #(1,-3,-5)# and #(-2,3-,4)#?
The distance is
The formula for the distance for 3-dimensional coordinates is similar or 2-dimensional; it is:
We have the two coordinates, so we can plug in the values for
(I wasn't sure if the
Now we simplify:
If you want to leave it in exact form, you can leave the distance as
Hope this helps!
