  1. Given first derivative: We are given the first derivative of yy with respect to xx as dydx=e5y\frac{dy}{dx} = e^{5y}. To find the second derivative d2ydx2\frac{d^{2}y}{dx^{2}}, we need to differentiate dydx\frac{dy}{dx} with respect to xx.
  2. Apply chain rule: Using the chain rule, we differentiate e5ye^{5y} with respect to xx. The chain rule states that the derivative of eue^{u} with respect to xx is eududxe^{u} \cdot \frac{du}{dx}, where uu is a function of xx. In this case, u=5yu = 5y, so we need to multiply e5ye^{5y} by the derivative of 5y5y with respect to xx, which is xx11.
  3. Substitute into expression: We already know that (dydx)=e5y(\frac{dy}{dx}) = e^{5y}, so we substitute this into our expression for the derivative of 5y5y with respect to xx. This gives us 5e5y5 \cdot e^{5y}.
  4. Find second derivative: Therefore, the second derivative d2ydx2\frac{d^2y}{dx^2} is e5y5e5ye^{5y} \cdot 5 \cdot e^{5y}, which simplifies to 5e10y5 \cdot e^{10y}.
