Answer 2

Scientific Notation

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

$a\times10^n$

• 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. $6.72\times10^5$      ⇒ $6.72\times10^5$
2. $67.2\times 10^{-4}$    ⇒ $6.72\times 10^{-3}$
3. $672\times 10^4$       ⇒ $6.72\times 10^6$
4. $0.000672$        ⇒ $6.72\times10^{-4}$

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

$6.72\times10^{-4}$

$6.72\times 10^{-3}$

$6.72\times10^5$

$6.72\times 10^6$

Finally, rewrite all the numbers as their given format:

$0.000672$

$67.2\times 10^{-4}$

$6.72\times10^5$

$672\times 10^4$

Answer

$0.000672$

$67.2\times 10^{-4}$

$6.72\times10^5$

$672\times 10^4$
