Step 1 :We are given the function \(y = x^{1/5}\).
Step 2 :We are asked to find the second derivative of this function.
Step 3 :First, we find the first derivative using the power rule for differentiation, which states that the derivative of \(x^n\) is \(n*x^{(n-1)}\).
Step 4 :Applying the power rule, we get the first derivative as \(y' = 0.2x^{-0.8}\).
Step 5 :Next, we find the second derivative by differentiating the first derivative.
Step 6 :Applying the power rule again, we get the second derivative as \(y'' = -0.16x^{-1.8}\).
Step 7 :Final Answer: The second derivative of the function \(y = x^{1/5}\) is \(\boxed{-\frac{0.16}{x^{1.8}}}\).
