#Roots with tetrartion and pentation
21 messages · Page 1 of 1 (latest)
I don't know of any way to compute the inverses of tetration or pentation like there are methods for computing logarithms and roots, but the wikipedia article seems to have a lot of information on them. https://en.wikipedia.org/wiki/Tetration#Inverse_operations
If you're interested in these higher order operations, you might be interested in this video. https://www.youtube.com/watch?v=ofy2Kw2sIZg
Why isn't exponentiation commutative? Or associative? Is exponentiation really the next operation after multiplication? Join me in this exploration of binary operations and ring theory.

this video presents an alternative to tetration that is much more satisfying.
I suppose an inverse to tetration would be to do x to the power of 1/(2 to the power of n ) with n being the number of times you square a number.
e.g 3 tetrated 3 times is 6561, 2 to the power of 3 is 8 and fittingly, the 8th root of 6561 is 3. Also 2 tetrated twice is 16. 2 to the power of 2 is four and the 4th root of 16 is 2.
Assuming pentation is to the power of 5, same thing but replace 2 with 5.
Ok so tetration is squaring the result of a squaring however many times yes
for example ((2x2)(2x2))(16)
(I can't do powers on my keyboard)
Alright so then the root increases exponentially
The first time you tetrate it's (xx)(xx)
the second time is (xx)(xx)(xx)(xx)
and the third time is (xx)(xx)(xx)(xx)(xx)(xx)(xx)(xx)
so to reverse it simply do whatever number your using's root of 2 to the power of however many times you multiplied x by x
5 ^ 7
well in maths you express a root as a power by doing x^1/root
What I want to know is do you understand why it works
because if you do then you'll have no problem using and applying it
Thanks
I appreciate your effort
