RE: Casio fx 5000F  Exponents
x^{n} does only accept positive integers, no negatives. the main difference to x^{y}, which accepts any numbers, is the designation on the display:
if you type 123 [x^{y}] 456 it shows up on the calc as 123x^{y}456, which calculates 123^456. so, x^{y} is kind of similar to our wellknown y^{x}  it raises one number to the power of the second number. the x^{n} key is more like a shift key. if you want the same result, you have to press 123 [x^{n}] 4 [x^{n}] 5 [x^{n}] 6 (note the second and the third x^{n}). This will be shown on the display as 123^{456} (with a tiny 4, 5 and 6, but without a special character for the x^{n} key. This can reduce the memory needed for stored formulas by one byte, and it looks nice  still it is of little use as far as i think.
