To solve the problem and prove that \(\frac{dy}{dx} = \frac{y^2 \log y}{x(1 - y \log x \log y)}\), we will follow these steps: ### Step 1: Define the function Let \( y = a^{x^{a^{x^{\cdots}}}} \). This means that \( y = a^{x^y} \) because the exponent itself is \( y \). **Hint:** Recognize that the infinite exponentiation can be simplified by substituting \( y \) back into the equation. ### Step 2: Take the logarithm of both sides ...
