The difference between the high end and low end of the range can be calculated by subtracting the low end from the high end:
2.329 × 10^(-2) cm per hour - 6.849 × 10^(-4) cm per hour
To subtract these values, we need to ensure that the exponents of 10 are the same. We can do this by multiplying 6.849 × 10^(-4) cm per hour by 100:
6.849 × 10^(-4) cm per hour * 100 = 6.849 × 10^(-2) cm per hour
Now, we can subtract:
2.329 × 10^(-2) cm per hour - 6.849 × 10^(-2) cm per hour = -4.52 × 10^(-2) cm per hour
Therefore, the difference between the high end and low end of the range is -4.52 × 10^(-2) cm per hour.
Human hair grows at a rate of about 6.849 × 10^(-4) cm per hour to 2.329 × 10^(-2) cm 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.
