Exponents Issue

[roadrunner]

On the emulator:

1. copy the expression from your first post in this thread and past onto the command line, click enter;
2. click on the expression;
3. click simplify;
4. click on the answer;
5. repeat from step 3.

I just now tried it on the handheld but keyed in the expression manually, it returned identical results.
