POWERS OF NUMBERS

[Dave Britten]

Interestingly, x^y makes it easier to calculate a sequence of powers, since you go from the "top" downward.

e.g.: 2^2^2^2 = 2^(2^(2^2))

On a 35: 2 ENTER 2 x^y 2 x^y 2 x^y

On a 45: 2 ENTER 2 y^x 2 x><y y^x 2 x><y y^x

Yes, I know there are other ways to do this specific example (fill the stack with 2, etc.), but you get the idea.
