Elementary query about 0^0

In trying to Plot a sum of terms of the form x^n where n runs from 0 to
something and the range of x includes the value x=0 I run into complaints
about 0^0 being indeterminate.  It often is, but shouldn't be considered so
in such cases.  I get round the difficulty by the hack of Unprotecting
Power, and then making definitions, four in all, such as
Power[0,0]=1,...,Power[0.0,0.0]=1, and then Protecting Power.  I put all
this in my init.m file.  Is there an easier way?  I feel I'm missing
something fantastically easy, but I can't find it in the books or Mma
literature.  Thanks for suggestions.
