Yi ting's height is 1.49 m. express this measurement in millimeters. explain your thinking. include equation with an exponent in your explanation.

1 meter = 100 centimeter
1 centimeter = 10 millimeters 

1.49 times 100 equals to 149 centimeter.
So 1.49 meter is the same as 149 centimeter.

149 times 10 equals to 1490 millimeters.
So 1490 millimeters is the same as 1.49 meters. 

1.49m = 1490mm
If we move the decimal point in 1.49 to the right three times (which is the same as multiplying 1.49 by 1000), this makes 1490. 
So, 1.49 times by 10^3 = 1490

10^3 means 10 times by itself three times. (10 times 10 times 10 which makes 1000)

The equation would be 1.49*10^3= 1490
(Note that * means multiply)
