Solution Steps

Step 1: Find the First Derivative

To find the first derivative \( f^{\prime}(x) \) of the function \( f(x) = (x^2 + 4)^6 \), we apply the chain rule. The result is: \[ f^{\prime}(x) = 12x(x^2 + 4)^5 \]

Step 2: Find the Second Derivative

Next, we differentiate the first derivative \( f^{\prime}(x) \) to obtain the second derivative \( f^{\prime \prime}(x) \). The calculation yields: \[ f^{\prime \prime}(x) = 120x^2(x^2 + 4)^4 + 12(x^2 + 4)^5 \]

Final Answer

Thus, the second derivative of the function is: \[ \boxed{f^{\prime \prime}(x) = 120x^2(x^2 + 4)^4 + 12(x^2 + 4)^5} \]
