TL;DR Summary
I have no clue about a LaTeX symbol at a Spanish thread.
Hi, PF

The scientific calculator I have is a Casio fx-82MS. At the keyboard, the ##\fbox {^}## button is the one provided to calculate powers.

My doubt is not my calculator: is a sentence at a native thread: "##x^{\blacksquare}## es la función" (the function is ##x^{\blacksquare}##). The question: What function, which key, and how does it work?.

I don't manage in my own language :confused:

All I see is "x to the power of ... black square".

Why don't you just direct us to the thread?

Sadly, I think youll have ask the poster directly. It could be almost anything although its likely x to the n or for a calculator x to the y or something similar.

The question: What function, which key, and how does it work?
The evaluation of; z = xy; z = x^y; is done via the logarithm and antilogarithm functions.
Z = Alog( Log( x ) * y ); The natural log is ln( x ); The natural antilog is e^( x ) .
