2) (9×8-2)÷7×4÷2=(72-2)÷7×4÷2=70÷7×4÷2=20

Answer 3

Let's simplify the expression step by step:

(14 ÷ 7 × 2 × 5 + 4) × 3 (9 × 8 - 2) ÷ 7 × 4 ÷ 2

1. Start by simplifying the expressions inside parentheses:

   = (2 × 2 × 5 + 4) × 3 (72 - 2) ÷ 7 × 4 ÷ 2 = (20 + 4) × 3 (70) ÷ 7 × 4 ÷ 2 = 24 × 3 (70) ÷ 7 × 4 ÷ 2 = 72 (70) ÷ 7 × 4 ÷ 2

2. Multiply the numbers outside the parentheses:

   = 5040 ÷ 7 × 4 ÷ 2

3. Divide:

   = 720 × 4 ÷ 2

4. Multiply:

   = 2880 ÷ 2

5. Divide:

   = 1440

So, the result of the expression is 1440.
