  If the exponent n is positive (n > 0), the n th power of zero is zero: 0 = 0.
  
  If the exponent n is negative (n < 0), the n th power of zero 0 is undefined, because it must equal 1 / 0 − n {\displaystyle 1/0^{-n}} with − n > 0, and this would be 1 / 0 {\displaystyle 1/0} according to above.
  
  The expression 0 is either defined as 1, or it is left undefined.
