A city has 1,489,000 people. What order of magnitude is this figure?1. 62. 73. 34. 5

Answer» Correct Answer - Option 1 : 6

The order of magnitude is the power of 10, when a number is written in its standard form. 

  • 500,000 in its standard form is:
  • 5.0×105
  • Hence, the order of magnitude is 5!

Just to clarify, the standard form of any number is that number written as a single digit followed by a decimal point and decimal places, which is multiplied with a power of 10.

Here are a few examples:

10=1.0×101

1489,000=1.489×106

Hence, the order of magnitude is 6.
