Abstract
In this article, we construct new Pad\'{e} approximations for the \emph{product} of binomial functions and powers of logarithmic functions. While several explicit Pad\'{e} approximants are known for powers of exponential functions, binomial functions, and logarithmic functions individually, an explicit Pad\'{e} construction for the product of these functions has not yet been directly achieved. Our main result yields arithmetic applications, providing new linear independence measures for linear forms in for and , where , , and . These results hold with algebraic coefficients in both the complex and -adic cases. Additionally, we establish that Pad\'{e} approximation of a single polylogarithm is, in general, perfect.
