### 2.3. Let \( g \) be a primitive root for \( \mathbb{F}_p \).
(a) Suppose that \( x = a \) and \( x = b \) are both integer solutions to the congruence \( g^x \equiv h \pmod{p} \). Prove that \( a \equiv b \pmod{p-1} \). Explain why this implies that the map (2.1) on page 63 is well-defined.

(b) Prove that \( \log_g(h_1 h_2) = \log_g(h_1) + \log_g(h_2) \) for all \( h_1, h_2 \in \mathbb{F}_p^* \).

(c) Prove that \( \log_g(h^n) = n \log_g(h) \) for all \( h \in \mathbb{F}_p^* \) and \( n \in \mathbb{Z} \).
