Final answer:
The distance from Earth to the moon of 239,000 miles written in scientific notation is 2.39 x 10µ miles. The distance from Earth to the moon, which is calculated to be 239,000 miles, can be written using scientific notation as 2.39 × 105 miles.
Step-by-step explanation:
To write the distance from the Earth to the moon in scientific notation, John's calculation of 239,000 miles must be expressed as a product of a number between 1 and 10 and a power of 10. To convert 239,000 to scientific notation, we move the decimal place 5 positions to the left (since it's currently not written, it's implicitly after the last zero). This gives us 2.39. We then multiply this by 10 raised to the power of 5, because we moved the decimal 5 places. So, the distance in scientific notation is 2.39 x 10µ miles.
The distance from Earth to the moon, which is calculated to be 239,000 miles, can be written using scientific notation as 2.39 × 10^5 miles.
The distance from Earth to the moon, which is calculated to be 239,000 miles, can be written using scientific notation as 2.39 × 105 miles.
