Answer 3

To calculate the expressions given, we'll perform the operations step-by-step. It seems like there might be a typo in the second expression, as it doesn't appear to be a standard mathematical operation. I'll interpret it as a subtraction, but if it's something else, please let me know.

1. 256 + 500 ÷ 27: First, perform the division: 500 ÷ 27 ≈ 18.5185 (rounded to four decimal places) Now, add 256 to the result: 256 + 18.5185 ≈ 274.5185 (rounded to four decimal places)

2. 106 - 110.786256626 ÷ 80713888 ÷ 2484415: Let's start with the division inside the parentheses: 110.786256626 ÷ 80713888 ≈ 0.000001373 (rounded to nine decimal places) Now, divide the previous result by 2484415: 0.000001373 ÷ 2484415 ≈ 5.5225e-13 (rounded to scientific notation)

   Finally, perform the subtraction: 106 - 5.5225e-13 ≈ 106 (rounded to three decimal places)

3. 250 ÷ 725224448 × 56: Start with the division: 250 ÷ 725224448 ≈ 3.448e-07 (rounded to scientific notation) Now, multiply the previous result by 56: 3.448e-07 × 56 ≈ 1.929088e-05 (rounded to scientific notation)

Here are the results of each expression:

1. 256 + 500 ÷ 27 ≈ 274.5185
2. 106 - 110.786256626 ÷ 80713888 ÷ 2484415 ≈ 106
3. 250 ÷ 725224448 × 56 ≈ 1.929088e-05 (in scientific notation)

Note: I've rounded the decimal results to a reasonable number of decimal places for clarity.
