1. Problem Description

The problem states that the distance from Earth to the Moon is approximately 382,500,000382,500,000 meters. We need to express this distance in scientific notation.

2. Solution Steps

To write a number in scientific notation, we express it in the form a×10na \times 10^n, where 1a<101 \le a < 10 and nn is an integer.
First, we write the given number: 382,500,000382,500,000.
Move the decimal point to the left until we have a number between 1 and
1

0. In this case, we move the decimal point 8 places to the left to get $3.825$.

Therefore, a=3.825a = 3.825.
Since we moved the decimal point 8 places to the left, we multiply by 10810^8.
Thus, 382,500,000=3.825×108382,500,000 = 3.825 \times 10^8.
The problem asks for an approximate distance, so we can round 3.825 to

4. Therefore, the approximate distance in scientific notation is $4 \times 10^8$ meters.

3. Final Answer

4×1084 \times 10^8 meters
