how to write power function on factorial?

I have to write this function.

f(0)= 4(0)! (1103+26390(0))/ (0!)^(4)396^(4)(0)

and that's how i wrote it

f(0)= [4* factorial(0)(1103+26390*0)]/[factorial(0)^(4)*396^(4)]

but it keep showing this error

()-indexing must appear last in an index expression.

f = @(x) 4 * factorial(x) .* (1103+26390*x) ./ (factorial(x).^(4).*396.^(4));
