Answer:

a = 3.7464

b = 16

Step-by-step explanation:

Given

See attachment for complete question

Required

Express the answer in a * 10^b

From the question, we have:

People = 4.46 * 10^9

Breath = 8.4 * 10^6 breath/person in a year

The number of breath is calculated by:

Overall = People * Breath

So, we have:

Overall = 4.46 * 10^9 * 8.4 * 10^6

Reorder

Overall = 4.46  * 8.4* 10^9 * 10^6

Overall = 37.464* 10^{9+6}

Overall = 37.464* 10^{15}

Using scientific notation a * 10^b;

The value (a) must be in the following interval 0 \le a \le 1

So, we have:

Overall = 3.7464 * 10 * 10^{15

Overall = 3.7464 * 10^{16

By comparing the above with: a * 10^b

a = 3.7464

b = 16
