Answer:
3.75 x 10^7
a = 3.745 (rounded) or 3.7464 (exact)
b = 7
Step-by-step 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
a = 4, b= 9. Explanation: Since all of it is to the power of 3, we can divide the exponents to of the results (right side of the equation). 12/3=4, 27/3=9. Hope this helps.
