Solution:   Leave us a comment of this math problem and its solution (i.e. if it is still somewhat unclear...): Math student
how can you write  r=a.(2/3)1/2
is this applicable for all plane equation? Dr Math
We found some bugs in this problem, but I think now is OK solution:

(x+a)2 + (y+a)2+(z-3a)2 = 6 a2 To solve this verbal math problem are needed these knowledge from mathematics:
