Benchmark test e^x^3

[Beginner]

Thank you for explaining the background. With the staggering improvements of the hardware from HP 50G via HP Prime G1 to HP Prime G2 is there any reason left for the limitations of the CAS?

If the HP 50G could do it, why should the HP Prime not be able to do it?

512 KB RAM, 2 MB flash, expandable via 2 GB SD card (HP 50G)
32 MB RAM, 256 MB flash (HP Prime G1)
256 MB RAM, 512 MB flash (HP Prime G2)

Also the hardware of the DM42 seems to be much simpler than the hardware of the HP Prime G2. If an improved free version if the software of the HP 42s can do it, why should the "flagship" HP Prime G2 not be able to cope with the task?
