	0^(a+bi)		2020-12-03
		Douglas pose la question : I realize raising 0^a = 0 if a>0 and undefined if a<=0. If have read that 0^bi is undefined for all b. What I don't understand is why 0^(a+bi) = 0 if a and b are not equal to zero. Is this purely by definition or is there a logical reason why this is the case? (I have taken Complex Analysis, so have a fairly good understanding of complex numbers.) Penny Nom lui répond.
	Is there an equation to find what percent of 0 is 1?		2020-03-09
		Asher pose la question : Question: Is there an equation to find what percent of 0 is 1. I remember learning quite a long time ago that the answer inst 0 and it isn't infinity. I'm pretty sure it was something like %=0 approaching infinity or %=1 approaching infinity. And I know it depends what value you assign the numbers i.e. dollars or temperature. Furthermore, is asking "what percent 1 dollar is of 0 dollars" the same question as "what percent profit do you make from selling something worth 0 dollars for 1 dollar." Thank you for your time and consideration -Asher Penny Nom lui répond.
