Question 513270
<font face="Times New Roman" size="+2">


Depends on what you are trying to represent.  Do you mean:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (2z)^0]


In which case you need to use the fact that:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ a^0\ =\ 1\ \forall\,a\,\in\ \mathbb{R}]


or do you mean:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (2z)\,\times\,0]


In which case you need to use the fact that:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ a\,\cdot\,0\ =\ 0\ \forall\,a\,\in\ \mathbb{R}]

*[tex \LARGE e^{i\pi} + 1 = 0]
