HI, thanks for the answer, but why 4?
i think it should be 8
4 i think
numbers inside the triangles are sq.roots of the sum of the numbers around the relevant triangles
Question Author
Hmmm.... 4 or 8? Any chance of some explanations?
4 i think
number inside any of the triangles is sq. root of sum of the numbers around that triangle
No, definitely 4 (each triangle can then be considered separately)
