Question

What is the order of magnitude of 600,000?

Answer 1

Orders of magnitude are expressed in powers of 10. 600,000 is `6 times 10^5` in standard form, so the order of magnitude of 600,000 is 5.

This is because powers of 10 have to be between 1 and 10, so it must be 6, and once multiplied by 10, it as then been raised to the power of 5, giving an order of magnitude of 5.
