Given positive integers x and n, return a positive integer, y, which is the nth term in the Juggler sequence beginning with x.
The Juggler sequence is defined by:
a(i+1) = floor(a(i)^0.5) , for even a(i).
a(i+1) = floor(a(i)^1.5) , for odd a(i).
For the purpose of this problem, the first element in the sequence is a(1) = x.
x = 3
n = 5
y = 6
