Answer 1

3.75 x 10^7

a = 3.745 (rounded) or 3.7464 (exact)

b = 7

Explanation:

Assuming you meant "a person takes 8.4 x 10^6 breaths

per year" we would multiply the number of people 4.46 x 10° by the number of breaths each person takes 8.4 x 10^6 and we get 37464000 and in scientific notation it would be 3.75 x 10^7
