Answer 2

The order of magnitude of 179 is 1.79 x 10^2.

Option (a) is correct.

Explanation:

• The order of magnitude means the power of 10.
• When a number has no decimal then the decimal place value is on the most left side of teh number.  
• In 179 the decimal place is after 9
• If we shift the decimal place value tone digit o the right side then we will add one power to 10.
• 17.9 x 10^1
• If we shift decimal place value two-digit to the right side then add two power to 10.
• 1.79 x 10^2  
• Thus the order of magnitude of 179 is 1.79 x 10^2.
