Zero to the zeroth power
GeoGebra evaluates 0^0 to 1, which is not correct, or at least there is no consensus on this. Moreover, when you try to raise zero to a negative power, the program just outputs infinity. 0^0 is evaluated to 1 in the Algebra and Spreadsheet view. In CAS, 0^0 just returns a question mark, so there's also a lack of consistency.
Was this intended to work like this?
