We are given the equation:

$\log_{2}\left(\log_{2}(x)\right) = 4$

Step 1: Solve the outer logarithmic equation

First, solve the equation $\log_{2}(y) = 4$ where $y = \log_{2}(x)$. This is done by rewriting the logarithmic equation in its exponential form:

$y = 2^4 = 16$

Thus, $\log_{2}(x) = 16$.

Step 2: Solve the inner logarithmic equation

Now that we have $\log_{2}(x) = 16$, rewrite this in exponential form:

$x = 2^{16} = 65536$

Final Answer:

The solution is:

$x = 65536$
