Tetration
Writing functions:
tetration(a, n)
In mathematics terrace or hyperoperation-4 is an iterative function exhibitors, the following hyperoperation after exponentiation. Terrace used to describe large numbers.
For any positive real number, a > 0 and nonnegative integer, the titration na you can determine recurrently:
na = 1 (если n = 0)
na = a
(n-1a) (если
n > 0)
According to this definition, calculation titration recorded as «power tower», exponentiation begins with the farthest to the initial levels (in this notation, with the highest exponent):
42 = 2(2(22)) = 65536
