= limrn→0Log(N(rn)) / Log(1/rn) |
| = limn→∞Log(N(rn)) / Log(1/rn) |
| = limn→:∞Log(N((1/3)n)) / Log(1/((1/3)n)) |
| = limn→∞Log(3⋅4n-1) / Log(3n) |
| = limn→∞((n-1)⋅Log(4) + Log(3)) / (n⋅Log(3)) |
| = limn→∞(n⋅Log(4) - Log(4) + Log(3)) / (n⋅Log(3)) |
| = limn→∞(n⋅Log(4))/(n⋅Log(3)) + (-Log(4) + Log(3))/(n⋅Log(3)) |
| = Log(4)/Log(3) ≈ 1.26186 |
