Some interesting observations:

A lot of calculators apparently get nested powers wrong and treat this as (n^5)^2 instead of the correct n^(5^2). I tried this on my Sharp PC-1475 in double-precision mode and couldn't figure out at first why I was getting such larger results! Turns out it's because the Sharp interprets it correctly.

Also, the TI-84 maintains the full 14-digit precision (and gets the correct result of ...5376 on the last term), but only displays 10-digit mantissas on the home screen. But if you use the seq() function to generate and store a list, then pull it up in the stat editor, you can scroll to the bottom elements and hit enter to see them displayed with the full precision.
