Answer 2

Let's break down the given expression step by step:

1. Start with the innermost parentheses: 18 × 3 = 54. Now the expression becomes: 125:(72:12×3+98:(68-54))

2. Next, calculate the subtraction inside the second set of parentheses: 68 - 54 = 14. The expression now becomes: 125:(72:12×3+98:14)

3. Now, let's simplify the division first: 72 ÷ 12 = 6. The expression becomes: 125:(6×3+98:14)

4. Moving on to the second division: 98 ÷ 14 = 7. The expression becomes: 125:(6×3+7)

5. Multiplication: 6 × 3 = 18. The expression becomes: 125:(18+7)

6. Addition: 18 + 7 = 25. The expression becomes: 125:25

7. Finally, perform the division: 125 ÷ 25 = 5.

Therefore, the value of the expression 125:(72:12×3+98:(68-18×3)) is 5.
