Yes, just cc the community (or reply to all), so that all the discussion is archived as a thread by the mailing list system.
It’s easier for users to search for an answer when there are no missing messages in the thread.
The answer to a problem/bug should be public. Sending a mail to only one person from the list is okay though, but only for private/off topic discussions.
