The expression in the image can be interpreted as:

$40 \div 5 \cdot 2 \times \left[ 18 \div 6 \times (12 - 9) \cdot 5 - (3 - 8) \right] \div 25$

Let's break it down step by step:

1. Inside the parentheses:
   • $12 - 9 = 3$
   • $3 - 8 = -5$

Now the expression becomes:

$40 \div 5 \cdot 2 \times \left[ 18 \div 6 \times 3 \cdot 5 - (-5) \right] \div 25$

2. Perform divisions and multiplications inside the brackets:
   • $18 \div 6 = 3$
   • $3 \times 3 = 9$
   • $9 \times 5 = 45$

Now the expression becomes:

$40 \div 5 \cdot 2 \times \left[ 45 + 5 \right] \div 25$

3. Addition inside the brackets:
   • $45 + 5 = 50$

Now the expression becomes:

$40 \div 5 \cdot 2 \times 50 \div 25$

4. Solve the operations from left to right:
   • $40 \div 5 = 8$
   • $8 \cdot 2 = 16$
   • $16 \times 50 = 800$
   • $800 \div 25 = 32$

Final Answer:

The value of the expression is $\boxed{32}$.
