Just remove the backticks and quotes around hostname?
for i in server1 server2;do ssh root@$i hostname;done
The backticks tell the shell (on your machine) to run the command inside
the backticks and replace that part of the command line with the output
of the command so you actually end up with a command line like:
for i in server1 server2;do ssh root@$i mylocalhostname;done.
