Hints/Tips re: Puzzle Solution | Comment 2 of 4 |
(In reply to Puzzle Solution by K Sengupta)

A^2*B^2*C^2 = 18*36*72 = 18^2* 2*72 = 18^2*12^2
=> ABC = 18*12 = 216

Since you took a square root and the problem domain is all integers, there is also the branch ABC=-216.
From there A=-6 -> x=-7; B=-3 -> y=-4; and C=-12 -> z=-13.
Then a second solution is found (x,y,z)=(-7,-4,-13).
