Answer 3

Let's solve each of these mathematical expressions step by step:

1. (39000 + 530 × 400/100)^2

   First, calculate the expression inside the parentheses: 39000 + 530 × 400/100 = 39000 + 2120 = 41120

   Now, square the result: 41120^2 = 1,690,054,400

2. (154000 + 840 × 300) / 10

   First, calculate the expression inside the parentheses: 154000 + 840 × 300 = 154000 + 252000 = 406000

   Now, divide the result by 10: 406000 / 10 = 40,600

3. 5264 / 7 × 304.4384 / 8 × 50

   First, perform the divisions and multiplications from left to right: (5264 / 7) × (304.4384 / 8) × 50 = (751.42857) × (38.0548) × 50

   Now, multiply the results: (751.42857) × (38.0548) × 50 ≈ 1,432,105.1428

So, the results of the three expressions are:

1. 1,690,054,400
2. 40,600
3. Approximately 1,432,105.1428
