Use the following information to complete parts i, ii, and iii.

1 hour= 3,600 seconds

1 year= 31,556,952 seconds

part i: use scientific notation to estimate the number of hours in one year.

part ii: use scientific notation to calculate the exact number of hours in one year.

part iii: in two or more complete sentences, compare your answers to parts i and ii. in your comparison, discuss similarities and differences in your answers.

For part one, round the number of seconds in a year, to an easy number, depending on how many significant figure then divide that by 3600, the number of seconds in an hour to get the number of hours in a year. for part 2 do the same but use the exact number instead of the rounded, scientific notation is expressed by using a number between 1 and 10 multiplied by a power of 10 which is how many digits to the left (positive exponent) or right (negative exponent) you must move to get a number from 1 to 10
for part three just explain what is the same or different about your 2 answers.
