Query: An Explanation of Mellin's 1921 Paper   In 1921 Mellin published a Comptes Rendu paper computing the principal root
of the polynomial $Z^n + x_1Z^{n_1} + \cdots + x_pZ^{n_p} - 1$ using
hypergeometric functions of its coefficients $x_1,...,x_p.$ He used an integral
transform nowadays bearing his name. Slightly over three pages, the paper is
written in French in a terse style befitting the language. Unable to find an
elementary explanation on the web or in a texbook, we wrote this expository
article to make Mellin's landmark result accessible to interested people who
are not experts in hypergeometric functions and complex analysis.
