Let a(k)=(pi)^(.5^k)
Evaluate the expression a(k)-1 for the following values of k: 0, 1, 2, 3 , 10, 20, 50, 100.
Find the smallest k for which the expression is negative
Specify your estimate of results’ accuracy.

I think Ady is alluding to pi^.5 as possibly being the negative square root of pi, and similarly for other odd values of k.
