\(C=\left(0,5\right)^{-4}-625^{0,25}-\left(2\frac{1}{4}\right)^{-1\frac{1}{2}}+19\left(-3\right)^{-3}=\left(2^{-1}\right)^{-4}-\left(5^4\right)^{\frac{1}{4}}-\left[\left(\frac{3}{2}\right)^2\right]^{-\frac{3}{2}}+19.\frac{1}{\left(-3\right)^3}\)

\(C=\left(0,5\right)^{-4}-625^{0,25}-\left(2\frac{1}{4}\right)^{-1\frac{1}{2}}+19.\left(-3\right)^{-3}\)
\(=\left(\frac{1}{2}\right)^{-4}-625^{\frac{1}{4}}-\left(\frac{9}{4}\right)^{-\frac{3}{2}}+19.\left(-3\right)^{-3}\)
\(=2^4-\sqrt[4]{625}-\left(\frac{4}{9}\right)^{\frac{3}{2}}+19.\left(\frac{1}{\left(-3\right)^3}\right)\)
=\(16-5-\sqrt[2]{\left(\frac{4}{9}\right)^3}+19.\frac{1}{-27}=11-\frac{8}{27}-\frac{19}{27}=10\)
