# Understanding complex conjugates…

Is it right? $$\overline{(-1+i)} = (1-i) \\ \sqrt[4]{-625} = \pm5i$$
And what does n in this equation means? $$z = -\sqrt2 -\sqrt2i \\n= 9$$ Is it some sort of misunderstanding or am I missing something?

Note that $\overline{(-1+i)}$ is actually $-1-i$, not $1-i$. –  Stefan Geschke Feb 29 '12 at 21:17
There's not enough information in your question to figure out what $n$ means. Could you explain what you're working on? –  Jonas Kibelbek Feb 29 '12 at 21:29

$$\overline{-1+i} = -1-i$$
