If I am converting 0.0023 gigameters to centimeters, what would the answer be in scientific notation?

Question

Convert 0.0023 gigameters to centimeters. Include your answer in scientific notation.

Answer 1

0.0023 gigameters = 0.0023 × 10⁹ meters or 2.3 × 10⁶ meters in scientific notation.

 

Converting to centimeters:

 

2.3 × 10⁶ meters × (10² centimeters/1 meter) = 2.3 × 10⁶ × 10² centimeters = 2.3 × 10⁶⁺² centimeters = 2.3 × 10⁸ centimeters.

Answer 2

One gigameter = 10⁹ meters and 1 meter = 10² cm, so 1 gigameter = 10⁹*10² = 10¹¹ cm

 

0.0023 gigameters = (2.3 * 10^-3 gigameters) * 10¹¹ cm/gm = 2.3*10⁸ cm
