5

Explicación paso a paso:

$=\left(\frac{5}{\frac{x}{\frac{x}{x}+5}+5}+5\right)\frac{x^4-x^3}{x^4-1}\\\\\\=\frac{x^4-x^3}{x^4-1}\left(\frac{5}{\frac{x}{1+5}+5}+5\right)\\\\\\=\frac{x^4-x^3}{x^4-1}\left(\frac{30}{x+30}+5\right)\\\\\\=\frac{x^3}{\left(x^2+1\right)\left(x+1\right)}\left(\frac{30}{x+30}+5\right)\\\\\\=\frac{x^3\left(\frac{30}{x+30}+5\right)}{\left(x^2+1\right)\left(x+1\right)}$

$=\frac{\frac{x^3\left(5x+180\right)}{x+30}}{\left(x^2+1\right)\left(x+1\right)}\\\\\\=\frac{\left(5x+180\right)x^3}{\left(x+30\right)\left(x^2+1\right)\left(x+1\right)}$  =  5
