(23573-8999):21•7:(338+9)•29

Let's break down the expression step by step.

1. Evaluate the subtraction in the first part: \( 23573 - 8999 = 14574 \)

2. Now, divide by 21: \( 14574 \div 21 = 694 \) (using long division or a calculator)

3. Next, evaluate the addition in the next part: \( 338 + 9 = 347 \)

4. Now we have: \( 694 \cdot 7 \cdot 347 \cdot 29 \)

5. Compute \( 694 \cdot 7 \): \( 694 \cdot 7 = 4868 \)

6. Now compute \( 4868 \cdot 347 \): \( 4868 \cdot 347 = 1,689,596 \)

7. Finally, compute \( 1,689,596 \cdot 29 \): \( 1,689,596 \cdot 29 = 48,014,284 \)

Thus, the value of the expression \( (23573-8999):21•7:(338+9)•29 \) is 48,014,284.
