In 2009, the United States government spent more than it had collected in taxes, resulting in a budget deficit of $1.35 trillion. In Exercise, you will use scientific notation to put a number like 1.35 trillion in perspective. Use 1012 for 1 trillion.

Use your scientifi c notation answers from Exercises 1 and 2 to answer this question: How many years is 1.35 trillion seconds? Round to the nearest year. (Note: 1.35 trillion seconds would take us back in time to a period when Neanderthals were using stones to make tools.)

Exercise 1

Express 1.35 trillion in scientific notation.

Exercise 2

There are approximately 32,000,000 seconds in a year. Express this number in scientific notation.
