Question about Texas Instruments TI-89 Calculator
Use the ^ key to insert a power (it's located above the division key) then put a negative power by typing the negative key (located at the very bottom right of the keypad next to the ENTER key) and then the number of the power.
If this doesn't give the right result, put the negative power in parentheses. I can't remember off hand if you need to do that or not.
