The expression \((-9x)^0\) simplifies to 1.

This is because any non-zero number raised to the power of 0 equals 1, according to the zero exponent rule. 

\[
(-9x)^0 = 1
\]

Would you like more details on this rule, or do you have any other questions?

Here are 5 related questions:
1. What happens when an expression like \( (-9x)^1 \) is simplified?
2. How would you simplify \( (-9x)^2 \)?
3. What is the value of \( 0^0 \), and why is it considered an indeterminate form?
4. How does the zero exponent rule apply to negative bases, such as \( (-3)^0 \)?
5. How would you simplify an expression like \( (-9x)^0 + 5 \)?

**Tip:** Remember that the zero exponent rule applies to any number except 0 itself; raising 0 to the power of 0 is undefined.
