Answered above in detail. You were wrong when you said "better". One is not better than the other. This was addressed above. You were wrong when you said "calculate the square root of 2". You didn't obtain √2 by your manipulations, but a different number, 2. The thought you expressed would be better written as: π/H² = 2 = 3.125/ה² which is a trivial rearrangement of the definitions of H and ה. Since the definitions use 2, this is not even calculating 2. This is recovering 2 from the definitions. For x ≠ 0, y ≠ 0 the definition z = √(y/x) means y/z² = x and x z² = y, even if x and y are a complex numbers. It's not a mathematical mystery.
