To convert kilometers to meters, you need to know that there are 1,000 meters in one kilometer. So, to convert 4.5 x 10^4 kilometers to meters, you can multiply 4.5 x 10^4 by 1,000.

Here's the step-by-step calculation:

4.5 x 10^4 km * 1,000 m/km = 4.5 x 10^4 * 1,000 m
= 4.5 x 10^4,000 m

The result is expressed in scientific notation as 4.5 x 10^7 meters.
