Final answer:
To compare the two salaries, divide Aaron Rodgers' salary by the backup quarterback's salary. The result shows that Aaron Rodgers' salary is 100 times greater than his backup's salary.
Step-by-step explanation:
To compare the two salaries, we need to divide Aaron Rodgers' salary by the backup quarterback's salary.
Aaron Rodgers' salary is 2.2 * 107 dollars, while the backup quarterback's salary is 6.3 * 105 dollars.
To divide these numbers in scientific notation, we need to subtract the exponents. So, 107 divided by 105 is 102.
Therefore, Aaron Rodgers' salary is 100 times greater than his backup's salary.
