What is the program steps use to solve this X^X=1000 change equation to X^X - 1000=0

Gamo, what keys would you press if you have a number in X and you now want to calculate X^X–1000? I think you know that.

[ENTER] [y^x] [EEX] 3 [–]

You can also replace the EEX 3 with, say, RCL 5 (assuming this is not used by the program) and store 1000 or any other number in R5.
This way you can solve for any Y without having to change the program:

[ENTER] [y^x] [RCL] 5 [–]

1000  [STO] 5
(run the program) => 4,5555...

4711  [STO] 5
(run the program) => 5,1563...

EEX 9  [STO] 5
(run the program) => 9,2950...
