TETRATE(a,n)
- is the base value.
- is power value.
is the base value.
is power value.Description
- This function shows the tetration value of the given number.
- In , is the base value and is the power value.
- The hyperoperation after exponentiation is Tetration.
- Tetration is called iterated exponentiation.
- The notation means the application of exponentiation times.
- For any positive real a>0 and non-negative integer we define by:
,
means 
the application of exponentiation 
times.
we define Failed to parse (unknown function "\begin{cases}"): {\displaystyle ^n{a} = \begin{cases} 1, & \mbox{if }n\mbox{ =0} \\ a^{a^{(n-1)}}, & \mbox{if }n\mbox{ >0} \\ \end{cases} }
Examples
- TETRATE (3,2) = 27
- TETRATE (4,3) = 1.3407807929942597e+154
- TETRATE (10,2) = 10000000000
