The scientific notation:

[tex]a\cdot10^n,\ 1\leq a < 10\ and\ n\in\mathbb{Z}[/tex]

1 m = 1,000 mm

18 m = 18,000 mm

[tex]1\underbrace{8000}_{\leftarrow4}=1.8000\cdot10^4=1.8\cdot10^4\\\\\boxed{18\ m=18000\ mm=1.8\cdot10^4\ mm}[/tex]

Here is your answer:

In order to find the answer you have to count how many zeros that are in the number.

  • [tex]18000[/tex]
  • [tex]0 = 3[/tex]
  • [tex]1.8 \times 10^4= [/tex]
  • Check your work:
  • [tex]1.8 \times 10^4= 18000[/tex]

Therefore your answer is "1.8 × 10^4."

Hope this helps!
