Casio fx -5000F - Exponents

[damaltor]

I have quite a lot of Casios, and the 5000f, too. This small number exponent is a function which, as far as i know, none of the other casios has (at least of the series - neither the 3000, 3600, 3800, 5000f has it). I must also say that i do not really see the need for the function, as x^y is enough for me.
