Let's break down and solve the expression step by step:

Given expression:

$\frac{{(6+3)^2 + (9 - 10 \div 5)}}{{10 - 16 \div 8 + 9}}$

Step 1: Simplify the numerator

1. Simplify inside the parentheses:

   • $6 + 3 = 9$
   • $9 - 10 \div 5$

2. Exponentiation:

   • $(6 + 3)^2 = 9^2 = 81$

3. Division inside the parentheses:

   • $10 \div 5 = 2$

4. Subtraction inside the parentheses:

   • $9 - 2 = 7$

5. Result for the numerator:

   • $81 + 7 = 88$

Step 2: Simplify the denominator

1. Division inside the denominator:

   • $16 \div 8 = 2$

2. Simplify inside the denominator:

   • $10 - 2 + 9 = 17$

Step 3: Combine numerator and denominator

$\frac{88}{17}$

This simplifies to:

$\frac{88}{17} \approx 5.176$

So, the result of the expression is approximately $5.176$.
