    Indices Notation
AI Thread Summary
The discussion centers on finding a notation equivalent to Sigma and Capital Pi for exponentiation. Participants explore the possibility of a notation that could succinctly represent the expression x1^x2^x3^...^xn. A suggested notation, $$\Xi_{i=1}^n x_i = x_1^{x_2^{x_3^{\cdots x_n}}}$$, is proposed but ultimately deemed inadequate. The consensus indicates that no widely accepted notation currently exists for this purpose. The conversation highlights the complexity of representing exponentiation in a similar manner to summation and multiplication.

Is there an equivalent notation to Capital Pi notation (multiplier) and Sigma notation (summer) for raising to the power?

e.g. x1^x2^x3^x4...^xn=Notation(i=1 to i=n)(xi)

Where "Notation" represents the symbol in question (analogous to Sigma for sums, Capital Pi for multiplication)?

You mean something like:
$$\Xi_{i=1}^n x_i = x_1^{x_2^{x_3^{\cdots x_n}}}$$ ... no.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Thread 'Unit Circle Double Angle Derivations'
Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
