@[lunjiahao](/user/779970) 对是我脑抽了，但是根据指数定义，难道 $0^n\ne0$？

>@[lunjiahao](/user/779970) $x=0$ 时有 $x^n=0$ ？
理论相等 $(n>0)$ 不记得能不能取等
by lunjiahao @ 2024-05-06 20:25:31
@[lunjiahao](/user/779970) 应该只有 $n\ge0$ 时 $0^n=0$

@[WydnksqhbD_3](/user/753481)
嗯

我记得看过一个高数里的定义叫扩展实数域，令 $x>0$ 则 $\dfrac{x}{0}=+\infty$，$\dfrac{-x}{0}=-\infty$
