Human hair grows at a rate of about 6.849 times 10-4 cm per hour to 2.329 times 10^-2 per hour. The rate depends on gender, genetics, age, and health. Find the difference between the high end and the low end of the range. Express your answer in scientific notation. Do not round your answer.

Answer 1

To find the difference between the high end and low end of the range, we simply subtract the low end from the high end:

2.329 x 10^-2 - 6.849 x 10^-4

= 2.329 x 10^-2 - 0.0006849

= 2.329 x 10^-2 - 6.849 x 10^-4

= 2.329 x 10^-2 - 0.0006849

= 0.02329 - 0.0006849

= 0.0226051

Therefore, the difference between the high end and the low end of the range is 0.0226051. expressed in scientific notation.
