Two cells are viewed and measured under a microscope. The approximate diameter of each cell is listed below.
- cell P: 5.0 × 10-4 meters
- cell Q: 3.0 × 10-5 meters
What is the approximate difference, in meters, between the diameter of cell P and the diameter of cell Q ?
The answer is 4.7 × 10-4 meters.
5.0 × 10-4 = 0.0005 and 3.0 × 10-5 = 0.00003
0.0005 - 0.00003 = 0.00047 = 4.7 × 10-4
