At where exactly are you stuck?Can someone explain to me how exactly this demonstration works?
This line should be:Note that Am⋅An−m=Am+(n−m)=Am
It means (in some dialect other than mine) "powers" (exponentiation).What do you mean by potentiation?
This assumes you have already proved that Am⋅An=Am+n, and uses the fact that you can divide both sides of an equation by a non-zero number.Can someone explain to me how exactly this demonstration works?
AmAn=An−m
Demonstration:
Note that Am⋅An−m=Am+(n−m)=Am
and since thenA=0 passing Am dividing the other side of the equality we find that AmAn=An−m
Ahh, first time to read the word "potentiation"!It means (in some dialect other than mine) "powers" (exponentiation).
Actually, I'm not sure I ever saw it before either; it was just obvious from my knowledge of Latin, and from the context. When I search for it, all I find is a page obviously written by a non-English speaker, and this comment on something similar. It looks like an attempted translation of Spanish potenciación, or something similar.Ahh, first time to read the word "potentiation"!
