Question

An average drop of blood contains about 1.6 x 10^4 white blood cells. A rare drop of blood contains about 5 x 10^4 white blood cells. What is the difference between the number of white blood cells in a rare drop of blood and the number of white blood cells in an average drop of blood?​

Answer 1

Answer:

3.4 x 10^4

Step-by-step explanation:

1.6 x 10^4 - 5 x 10^4 = -3.4 x 10^4

5 x 10^4 - 1.6 x 10^4 = 3.4 x 10^4
