We have the following groups: G: ℝ+ under multiplication H: ℝ under addition we check if log: G→H is isomorphic, first we check homomorphism: log(xy)=log(x)+log(y) by laws of logarithm, next we check if log is bijective, this is where Im stuck, how do I check for bijection in groups? please if able explain step by step in detail, thank you in advance

Question
We have the following groups:
G: ℝ+ under multiplication
H: ℝ under addition
we check if log: G→H is isomorphic, first we check homomorphism: log(xy)=log(x)+log(y) by laws of logarithm, next we check if log is bijective, this is where Im stuck, how do I check for bijection in groups? please if able explain step by step in detail, thank you in advance.
