Answer
$400,000,000$ meters
Work Step by Step
We need to expand the distance from the Earth to the Moon ($4\times 10^{8}$) as a whole number. This number is in Scientific Notation. To expand the number we simply write the digit "4" followed by the number of zeroes in the 10th power (in this case 8). Therefore, we have:
$4\times 10^{8}=400,000,000$ meters
