Group Homomorphism Proof (Example with e^x)

Показать описание
Consider the map f which takes x and sends it to e^x. This is a map from the group of reals under addition to the group of positive reals under multiplication. We prove this a group homomorphism.

pls
Have u taken course in it?

A little correction:

For the second group you mean (R\{0}, *) instead of (R, *). (R, *) is not a group of course, because 0 has no inverse here.
