Root dn is the dn with empty string ("") and root entry generally includes information about ldap server like supported controls, supported auth mechanisms etc.
"dc=example,dc=com" is an example of the domain name one level below the root dn.
Base dn concept is used for generally search operations and base dn implies the dn of the basis entry.
So Root dn is not dc=example,dc=com.
Base dn can be anything.
