This is a somewhat funny question. To explain the problem of complex extensions of the principal square root, I would like to have two visibly different square root signs within the same document; for example, besides the usual one, a boldface square root sign, yet hosting a normally typed argument. I have no clues. If not possible, I would be grateful for suggestions about totally different solutions...

Yes of course this can be done with the bm package. The usage is detailed in the package documentation section 3.3.

\documentclass{article}
\usepackage{amsmath}
\usepackage{bm}

\begin{document}

$\bm\sqrtsign{x} \quad \text{vs.} \quad \sqrt{x}$

\end{document}

enter image description here

However, I would urge you to come up with something a little bit more noticeable.

    strange as it may seem, I can be wrong (especially this time of night:-) I think I'll delete my answer in that case – David Carlisle May 4 '17 at 22:41
