$$ (1+\sqrt{5}+i \sqrt{10-2 \sqrt{5}})^5= $$

If the least positive integer $n$ satisfying the equation $\left(\frac{\sqrt{3}+i}{\sqrt{3}-i}\right)^n=-1$ is $p$ and the least positive integer $m$ satisfying the equation $\left(\frac{1-\sqrt{3 i}}{1+\sqrt{3} i}\right)^m=\operatorname{cis} \frac{2 \pi}{3}$ is $q$, then $\sqrt{p^2+q^2}=$

Sum of the squares of the imaginary roots of the equation $z^8-20 z^4+64=0$ is
