I don't remember seeing any strange behaviour for the x^y key so I guess they changed it between the fx-29 and fx-39,
although I no longer have the calculator to check.

Any AOS calculator that had [X<>Y] key cannot assume x^y = exp(y * ln(x)).
It had to wait until [=] key is pressed (or other operators, say + - x /)

So, based on googled fx-39 pictures, you will not see ln(x) intermediates.

Actually, it might have been an fx-110 I had, which was similar to the fx-39, but with extra digits on the display, and the angle/sd mode switch in a different place. EDIT: Probably not though, because I don't remember mine having a dB conversion function. I've not seen a dedicated dB conversion function on a calculator before!
