WebAug 16, 2024 · The isomorphism (R + to R) between the two groups is that ⋅ is translated into + and any positive real number a is translated to the logarithm of a. To translate back from R to R + , you invert the logarithm function. If base ten logarithms are used, an element of R, b, will be translated to 10b. Web3 are isomorphic. Evidence that they resemble each other is that both groups have order 6, three elements of order 2, and two elements of order 3 (and of course one element of order 1: the identity).
