Question

The radius of Earth is about 6.38 x 10³ kilometers. Write this distance in standard notation ​

Answer 1

6380km

Explanation:

10³ is just 1000 if you think about it.

6.38 multiplied by 1000 would just mean you need to move the decimal to the right 3 times.

Also if you look up the earth's radius on wikipedia, it says 6,371km which is close to 6,380km.

Answer 2

6.38 * 10^3 = 6380 kilometers.

Hope this helped!
