Editing Exponentiation (section)

===Zero exponent===
As mentioned earlier, a (nonzero) number raised to the {{math|0}} power is {{math|1}}:<ref>{{cite book |title=Technical Shop Mathematics |last1=Achatz |first1=Thomas |page=101 |date=2005 |edition=3rd |publisher=Industrial Press |isbn=978-0-8311-3086-2 |url=https://books.google.com/books?id=YOdtemSmzQQC&pg=PA101}}</ref><ref name=":1"/>
: <math>b^0=1.</math>

This value is also obtained by the [[empty product]] convention, which may be used in every [[algebraic structure]] with a multiplication that has an [[multiplicative identity|identity]]. This way the formula
: <math>b^{m+n}=b^m\cdot b^n</math>
also holds for <math>n=0</math>.

The case of {{math|0<sup>0</sup>}} is controversial. In contexts where only integer powers are considered, the value {{math|1}} is generally assigned to {{math|0<sup>0</sup>}} but, otherwise, the choice of whether to assign it a value and what value to assign may depend on context. {{Crossreference|For more details, see [[Zero to the power of zero]].}}
