Answer 2

Let's calculate the values for each expression:

1. 5 × 102.2: Answer: 511

2. (5 × 10).2: First, evaluate the expression inside the parentheses: 5 × 10 = 50. Then, multiply the result by 0.2: 50 × 0.2 = 10.

3. 7 × 23.3: Answer: 162.1

4. (7 × 2).3: First, evaluate the expression inside the parentheses: 7 × 2 = 14. Then, multiply the result by 3: 14 × 3 = 42.

5. 45 ÷ 3.3: Answer: 13.636363...

6. (45 ÷ 3).2: First, evaluate the expression inside the parentheses: 45 ÷ 3 = 15. Then, multiply the result by 2: 15 × 2 = 30.

7. 24 ÷ 23.3: Answer: 1.0295202952...

8. (24 ÷ 2).3: First, evaluate the expression inside the parentheses: 24 ÷ 2 = 12. Then, multiply the result by 3: 12 × 3 = 36.
