I: Scientific Notation: In each case report your answer in proper scientific notation as some number between 1 and 10 multiplied by 10 to some power.

1) 12000 = ?

2) 4200000000000 = ?

3) 0.005 = ?

4) 62300050600077242 = ?

5) 0.00000000000000022 = ?

II: Exponents: Here are a few problems to check that you are working with exponents effectively. In each case report your answer in proper scientific notation as some number between 1 and 10 multiplied by 10 to some power. For the ones where the numbers are simple do them both by hand and with a calculator to make sure your answers agree. In all cases determine the proper exponents without using a calculator to build your skills.

6) 1.104.3.102 = ?

7) 42.10-2.0.14.103 = ?

8) 6.2.104.3.8.10-7.5.102 = ?

III: Equation Manipulation: In each case "solve the equation" for the indicated variable. This means you should have a valid algebraic expression (not a number) for the indicated variable.

12) x=32 + 8t: Find an expression for t.

13) v=81t - 12: Find an expression for t.

14) 5x = 14t + 3: Find an expression for t.

15) a = 12v1/2 + 9: Find an expression for v.

16) 4x=5t(3/4): Find an expression for t.

IV: Scientific Prefixes: Match the correct exponential description from the list on the right with the appropriate term in the left list. Also match correct abbreviation for the prefix to the name.
