To find $h(h(h(x)))$, you need to define the function $h(x)$ first. Without a definition of $h(x)$, it's impossible to proceed. Could you provide the explicit form of the function $h(x)$?

Let me know if you need help with something else or if you'd like to proceed with defining $h(x)$.

Here are 5 questions that may help us:

1. What is the function $h(x)$?
2. Are there any specific constraints on $x$ in this problem?
3. Is this part of a larger problem involving compositions of functions?
4. Are you looking for a general form for any $h(x)$?
5. Would you like to evaluate $h(h(h(x)))$ for a specific value of $x$?

Tip: When working with function compositions, always simplify step by step to avoid confusion.
