Latest version.
<< 11 115 ^ 12 115 ^ / >> TEVAL
Time .9368 sec. At least it's less than a second.
I'll try a few more. This one is like the previous but entirely in Polish.

But this one is not generic.

I type it in on the 50 and evaluate, and while its busy move over to the Prime and have my answer long before it finishes.
~.0004s is the evaluation time for an exact result on the unit I just tested.

Perhaps a programming challenge for the Prime would reveal how brilliant it is?
The last time I checked my 38G could deal with sequences going from index 1 up to 10^12 - what's the range limit for the Prime?

Directly on the keyboard :time((11/15)^115) in CAS: 0.000424s.

My Prime (first version without data streamer ability) came up with 0.000406. The Android app (free version) on a Cat S60 clocked in at 0.000054. Fiftyfour microseconds iif I've not messed with my decimals :-)

Should you want to perform this calculation on a 40G/gs it's much faster if you enter
11^115/12^115
in CAS.

Another way (50G):
Code:
<< {'(&A/&B)^&C' , '&A^&C/&B^&C' } ↑MATCH << SIMPLIFY >> IFT >>Not so fast (1.9 sec) but I like it...

I never liked match.

There are some limitation in exact mode but I like it very much ;D It's a powerfull way to increase CAS functionality. An improve MATCH command on the PRIME could be _very_ powerful.
Working with 'pattern' is powerfull for manipuling symbolic structurs
