(a) First, we need to convert years to minutes because the heart rate is given in beats per minute. There are 60 minutes in an hour, 24 hours in a day, and 365 days in a year. So, 2 years is equal to 2*60*24*365 = 1,051,200 minutes.

Now, we can calculate the total number of heartbeats in 2 years by multiplying the average heart rate by the total number of minutes in 2 years. So, 72.0 beats/minute * 1,051,200 minutes = 75,686,400 beats.

(b) The question is asking for the number of beats in 2.00 years. The extra decimal places in the year value do not change the calculation because 2.00 years is the same as 2 years. So, the answer is still 75,686,400 beats.

(c) Similarly, the question is asking for the number of beats in 2.000 years. Again, the extra decimal places in the year value do not change the calculation because 2.000 years is the same as 2 years. So, the answer is still 75,686,400 beats.
