Question

What is 9,865 km expressed in scientific notation?

Answer 1

It's 9.865 * 10^3 . The first number has to be between 1 and 10, and then multiply the number by ten, so it's 9.865 times 10 to the power of 3. 

Answer 2

Hello there!

Scientific notification is when a number is between 1 and 10 times a power of 10.
In this case, your answer will be 9.865 x 10³ km or 9.865 x $10^{6}$.

Hope This Helps You!
Good Luck :)
