To convert the scientific notation \(2.05 \times 10^6\) into standard form, you can move the decimal point 6 places to the right:

  1. Start with \(2.05\).
  2. Move the decimal point 6 places to the right:
    • Move 1 place: 20.5
    • Move 2 places: 205
    • Move 3 places: 2050
    • Move 4 places: 20500
    • Move 5 places: 205000
    • Move 6 places: 2050000

Thus, \(2.05 \times 10^6\) in standard form is \(2050000\) feet.

The correct response is B: 2,050,000 feet.
