The calculated value of $E$ based on the given equation and parameters is approximately $66.14$.

Would you like more details on the calculation or have any other questions?

Here are five related questions for deeper exploration:

1. How would the result change if the value of $a$ were doubled?
2. What happens to $E$ if $X_{ino}$ is increased by 10%?
3. How does the expression behave as $a \to 0$?
4. Can this equation be simplified under specific conditions?
5. How does $E$ change with variations in $Z_0$?

Tip: In problems involving multiple variables, it's useful to understand how changes in individual variables affect the outcome.
