Take a look below to see the problem (at very end)
We have the equation:
X to the power of X to the power of X to the power of ... etc. equals 2
(1)
It is necessary to find the value of X.
Without falling into a stupor, but after thinking a little, we realize: in order to raise X to a power, it would be nice to know this power. Peering carefully at equation (1), we notice that the exponent is:Β
Again this endless expression... But after all (according to the problem statement) it is equal to 2β. Thus, equation (1) can be rewritten in a simpler way:Β
(2)
Now the solution is obvious: take the square root and get (we'll limit ourselves to 9 signs) πΒ
Bingo ! We got it!
But suddenly ...
a clever man appears and said:
- Let's solve this :Β
(3)
It is very similar to equation (1), only difference is: there is number four '4' instead of two '2'. Reasoning, as before, we write down:Β
Wow! Confusion! πΒ
Same answer
for both Eq.1 and Eq.3 (!?!?)Β
Numerical test
Ok, the solution for equation(1) is confirmed.
But what to do with equation (3) ???Β
