Pre-Test

Remember, this pre-test is designed to see if you already have the skills that are covered in this tutorial, so that you don't waste time. Peeking at the answers will do you no good! Work out the problems below on a separate sheet of paper and then check the answers. If you don't even have an idea of how to work the problems, then you should go right to the tutorial.

 

  1. Write the following numbers in scientific notation:

    1. 24,500

    2. 534,200,000

    3. 0.00000083

    4. 0.00643

  2. Write the following in decimal form:

    1. 7 X 104

    2. 6.3 X 107

    3. 2.84 X 10-3

    4. 3.6 X 10-8

    5. 1 X 105

    6. 5 X 100

  3. Multiply or divide the following:

    1. (2.3 X 106) X (9.4 X 102)

    2. (4.92 X 103) X (6.19 X 10-4)

    3. (5.5 X 108) / (5 X 102)

    4. (3.6 X 105) / (1.2 X 10-3)

  4. Add or subtract the following:

    1. (3.5 X 104) + (4.1 X 103)

    2. (7.46 X 105) + (1.65 X 103)

    3. (7.46 X 105) - (1.65 X 103)

    4. (7.21 X 10-3) - (4.29 X 10-5)

  5. Solve the following:

    1. (5.62 X 103)2 = ?

    2. 1 / (7.33 X 105) = ?

    3. square root of 9 X 104 =
