does not work when you exclude a math script like mathjax

I have a problem, mathjax is a js, but when I try to exclude it in this cache plugin, it does not work, can someone help me please? is a math script that is installed, then you write by means of mathematical equations code, but I try to exclude it from pagespeed ninja, and it does not work. Help.
