Possibly. Maybe use sort with a separator of "+", on the 2nd column -
this will give you the smallest exponential.  From there, sort the
duplicates with a separator of " " - only do this for the first
set of duplicates - haven't quite worked out how to do that.  
The first entry after this is then your answer.
