Differentiate and simplify: $y=\sqrt[5]{(\ln x)^{4}}$

Step 1 ：Given the function \(y=\sqrt[5]{(\ln x)^{4}}\)

Step 2 ：We can rewrite the function as \(y=(\ln x)^{4/5}\)

Step 3 ：Using the chain rule and the power rule, we differentiate the function

Step 4 ：The derivative of the function \(y=(\ln x)^{4/5}\) is \(0.8/(x*\ln(x)^{0.2})\)

Step 5 ：\(\boxed{0.8/(x*\ln(x)^{0.2})}\) is the simplified form of the derivative
