Scientific Notation

Scientific notation is a way of writing numbers that looks like the following:

[tex]a\times10^n[/tex]

  • a is any number between 1 and 10
  • n is any integer

For instance, we can write 2930 in scientific notation.

  1. First, move the decimal so that the number is between 1 and 10:
    ⇒ 2.93
  2. Notice how we moved the decimal 3 places to the left. This means n will be 3. (Note that when we move to the right, n would be negative.)
    ⇒ 2.93 × 10³

Solving the Question

First, write all the given values in scientific notation:

  1. [tex]6.72\times10^5[/tex]      ⇒ [tex]6.72\times10^5[/tex]
  2. [tex]67.2\times 10^{-4}[/tex]    ⇒ [tex]6.72\times 10^{-3}[/tex]
  3. [tex]672\times 10^4[/tex]       ⇒ [tex]6.72\times 10^6[/tex]
  4. [tex]0.000672[/tex]        ⇒ [tex]6.72\times10^{-4}[/tex]

Now, let's compare the values of n, and organize the numbers from least to greatest:

[tex]6.72\times10^{-4}[/tex]

[tex]6.72\times 10^{-3}[/tex]

[tex]6.72\times10^5[/tex]

[tex]6.72\times 10^6[/tex]

Finally, rewrite all the numbers as their given format:

[tex]0.000672[/tex]

[tex]67.2\times 10^{-4}[/tex]

[tex]6.72\times10^5[/tex]

[tex]672\times 10^4[/tex]

Answer

[tex]0.000672[/tex]

[tex]67.2\times 10^{-4}[/tex]

[tex]6.72\times10^5[/tex]

[tex]672\times 10^4[/tex]
