How does one raise a number to a power in the 9100A?

I have never used and not even seen an HP9100 in real life, but since there seems to be no power function you can simply do it the way most later calculators do it internally: y^x = e^x · ln y.

So in your example you calculate ln 3, multiply this by 201 and finally press e^x.

Especially for large results the last digit(s) maybe slightly off, just as on HP calculators with a power key up to the mid-Seventies – these use the same method.
