by

To multiply the numbers 20, 10, 4, 31, 10, and 20, follow these steps:

  1. Perform the multiplication step-by-step:
    • First, multiply 20 and 10:
      • 20 × 10 = 200
    • Now, multiply the result (200) by 4:
      • 200 × 4 = 800
    • Next, multiply 800 by 31:
      • 800 × 31 = 24800
    • Then, take 24800 and multiply it by 10:
      • 24800 × 10 = 248000
    • Finally, multiply 248000 by the last 20:
      • 248000 × 20 = 4960000

The total product is 4,960,000.

To express this result in scientific notation:

  • Identify the significant figures: 4.96
  • Count how many places the decimal point has moved to get to this position from its original position (6 places to the left).

Therefore, the scientific notation for 4,960,000 is:

4.96 × 106

So, the final answer for the multiplication of 20, 10, 4, 31, 10, and 20 expressed in scientific notation is 4.96 × 106.
