Basic Q's I've read the user manual and the tips and tricks paper that came with the calculator but I still can't seem to understand how to do these 2 things. 1. display things like 9 to the 16th power or 3 to the 12th power I can only do like 10 to the 9th power, 10 to the 7th power, etc... 2. store and recall a constant is it possible to store a value and then instead of having to continually retype in the value just press something to bring the value up again (for adding long strings of numbers...) Thanks!

The LOG and LN keys do what you have done.
To get 9 to the 16th power, enter 9, "y to the power x" (under the OFF key) then 16, then =
3 to the 12th power is the same, enter 3, y to the power x, 12, =, result 531,441
The inverse key sequence: value 1, 2nd, y to the power x, value 2, returns the xth root of y, e.g. 531,441, 2nd, y to the power x, 12, =, gives you 3 back
