Answer 3

To solve the given expression, let's break it down step by step:

Step 1: Simplify the innermost parentheses. -3,8 + 3/61 × 40 = -3,8 + (3/61) × 40 = -3,8 + (120/61) = -3,8 + 1,96721311 ≈ -1,83278689

-3,8 + 9/64 × 40 = -3,8 + (9/64) × 40 = -3,8 + (360/64) = -3,8 + 5,625 ≈ 1,825

Step 2: Simplify the expression inside the outermost parentheses. (-1,2 × (-1,83278689)) – (21 1/3 × 1,825) = -1,2 × (-1,83278689) – (21 + 1/3) × 1,825

Step 3: Simplify the multiplications and subtractions. -1,2 × (-1,83278689) ≈ 2,19934427

(21 + 1/3) × 1,825 = (63/3 + 1/3) × 1,825 = (64/3) × 1,825 = 117.33333333 × 1,825 ≈ 213.96875

Now, let's substitute the simplified values into the expression: 2,19934427 - 213.96875

Finally, we can subtract the two values: 2,19934427 - 213.96875 ≈ 1985.375593

Therefore, the result of the given expression is approximately 1985.375593.
