16^16 = 2^64. We can estimate that. Every 10
powers of 2 is 3 powers of
10. So 2^64 ~= 2^4 * 10^18. Or about 1.6*10^19. According to my HP48 it's
actually 1.845*10^19.
This calculation is particularly well suited to my Texas Instruments
SR-22 desk calculator. 16^16 = (16^8)^2. With the calculator in HEX
Hmmm. I am nto clever enough to use TI calcualtors, or anything else with
an '=' key. On the other hand my HP16C does much the same thing.
mode, enter 100000000. Now square it by pressing X
twice. Read 1. 10
in the display. That's 1x16^0x10. Now convert it to decimal with the
DEC key. The above number appears about a second later. There's
something about those 7-segment neon digits...
Why nmot just enter 16 (in decimal mode) and sqaure it 4 times?
