@[lunjiahao](/user/779970) $x=0$ 时有 $x^n=0$?
by WydnksqhbD_3 @ 2024-05-06 20:01:05


@[WydnksqhbD_3](/user/753481) 好像没有定义?(不是很懂) $$x^n=0 \implies n=\log_x 0$$ 但是 $n=\log_x y\ (x \not = 1 ,x>0)$ (我不确定有没有推错owo)

@[WydnksqhbD_3](/user/753481) $n>0$,不记得能不能取等
by lunjiahao @ 2024-05-06 20:12:30


@[lunjiahao](/user/779970) 定义出问题了?对数 $\log_aN$ 似乎不允许 $N\le0$

@[WydnksqhbD_3](/user/753481) 是吧?

@[lunjiahao](/user/779970) 高中课本是这么写的好像(说不定是 $a>0$)
by WydnksqhbD_3 @ 2024-05-06 20:16:39


@[WydnksqhbD_3](/user/753481) ?我表达的不是 $a>0$ 且 $a \not = 1$ 吗()
