Scientific Notation

Post-Test

This post-test is designed how well you have mastered the skills covered in this tutorial, to see if there are things your still need to work on. 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 some of the problems, then you should probably go back to the tutorial.

 

  1. Write the following numbers in scientific notation:

    1. 654,000

    2. 0.000000251

    3. 7,530,000,000

    4. 100

    5. 0.0081

    6. 1

  2. Write the following in decimal form:

    1. 4 X 105

    2. 3.4 X 10-6

    3. 4.84 X 10-9

    4. 7.12 X 1013

    5. 1 X 103

  3. Multiply or divide the following:

    1. (6.1 X 105) X (1.7 X 103)

    2. (7.82 X 1024) X (-3.79 X 10-15)

    3. (8.13 X 10-11) X (3.45 X 10-21)

    4. (6.98 X 107) / (-4 X 1013)

    5. (5.2 X 107) / (6.15 X 10-5)

    6. (-8.72 X 1015) / (-3.73 X 10-12)

  4. Add or subtract the following:

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

    2. (6.23 X 10-6) + (1.75 X 10-4)

    3. (5.37 X 1010) + (6.79 X 1012)

    4. (8.45 X 108) - (3.94 X 106)

    5. (7.22 X 10-6) - (8.21 X 10-7)

    6. (9.43 X 106) - (2.78 X 108)

  5. Solve the following:

    1. (8.77 X 104)2 = ?

    2. (3.46 X 10-3)3 = ?

    3. 1 / (4.305 X 105) = ?

    4. 1 / (8.19 X 10-8) = ?

    5. square root of 3.49 X 106 =

    6. square root of 7.53 X 109 =

    7. cube root of 2.56 X 1020 =

     

Now you can check your answers
