Calculus Level 4

Find the value of $$x$$ satisfying the equation below.

$\large \dfrac{(\sqrt[0!]{2016^{\pi^{0}}})(\sqrt[1!]{2016^{\pi^{1}}})(\sqrt[4!]{2016^{\pi^{4}}})(\sqrt[5!]{2016^{\pi^{5}}})(\sqrt[8!]{2016^{\pi^{8}}})(\sqrt[9!]{2016^{\pi^{9}}})(\dots)}{(\sqrt[2!]{2016^{\pi^{2}}})(\sqrt[3!]{2016^{\pi^{3}}})(\sqrt[6!]{2016^{\pi^{6}}})(\sqrt[7!]{2016^{\pi^{7}}})(\sqrt[10!]{2016^{\pi^{10}}})(\sqrt[11!]{2016^{\pi^{11}}})(\dots)}=2016^{x}$

Notation : $$n!$$ denotes the factorial function. For example, $$8! = 1\times2\times3\times\cdots\times8$$.
