1 answer

The radius of Neptune, approximately 15,300 miles, can be expressed in scientific notation as \( 1.53 \times 10^4 \) miles.

Here's how that is done:

  • Move the decimal point in 15,300 two places to the left to get 1.53.
  • Count how many places you moved the decimal point (which is 4).
  • Thus, you express it as \( 1.53 \times 10^4 \).
