The image text extraction wasn't very clear. However, from visual inspection, the equation appears to be:

$\left( \frac{18^2 \cdot 81^3}{4 \cdot 3^{15}} \right)^2$

I'll now simplify and solve this expression.There was a small issue with the approach I took to simplify the expression. I'll correct it by using symbolic math to ensure the simplification process works properly. Let's try again.The simplified result of the expression is $9$.

Would you like any further details or clarifications?

Here are some related questions to expand your understanding:

1. How do exponent rules apply when simplifying expressions with powers?
2. What are the properties of powers when dealing with both multiplication and division in the same expression?
3. How does squaring a fraction impact both the numerator and denominator?
4. How can simplifying exponents help in more complex algebraic expressions?
5. What are the techniques to factorize expressions involving powers?

Tip: When dealing with large exponents, try to simplify the base first by factoring it into prime numbers, which can make exponent rules easier to apply.
