2. To make a fraction with a negative exponent: 1) Place a one over the number with the exponent. 2) Multiply the exponent out underneath. Scientific to Standard Notation and Back Again

3. Write in fraction form.

4. Write in scientific notation. 1) Only one digit can be in front of the decimal. 2) Write all remaining numbers until you reach all the zeros in a row. 3) Write a multiplication sign. 4) Place the 10 with the appropriate power.

5. A) 15,010 B) 0.0092 C) 960,000 D) 7,096,000,000 E) 0.00000000002

6. To change from Scientific to Standard Notation: Look at the exponent *The number tells you how many places to move the decimal. *The sign tells you which way to move the decimal Positive – move to the right Negative – move to the left

7. Write in standard notation. a) 3.79 x 10 3 b) 2.506 x 10 -5 c) 3 x 10 7 d) 4.2 x 10 -11 e) 5 x 10 -2

8. Hint: Think money to help with exponents with scientific notation!! If it is a lot of money you would be positive, therefore a positive exponent. If a tiny decimal number, you would be negative if that is how much money you had, so a negative exponent.
