Just connect to the database in which you are interested, open a new query window, and enter the following query:
SELECT SERVERPROPERTY('ProductVersion') as 'Product Version',
SERVERPROPERTY('ProductLevel') as 'Product Level',
SERVERPROPERTY('Edition') as 'Edition'
For me, this produced the following:
12 Product Version Product Level Edition10.50.1600.1 RTM Enterprise Edition (64-bit)
