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

$$ \overline{-1+i} = -1-i $$ The complex conjugate flips the sign of the imaginary part. To find the nth root of a number, express in polar form first. The rest should be simple. You can easily check your answer by taking your result to the 4th power and seeing if it agrees. |
