Select the correct answer.

Which of these numbers is the most precise approximation of [tex]\sqrt{12}[/tex]?

A. 3.0
B. 3.446
C. 3.46
D. 3.464



Answer :

To determine the most precise approximation of [tex]\(\sqrt{12}\)[/tex] among the given options, let's analyze each value:

1. Firstly, note that [tex]\(\sqrt{12}\)[/tex] is an irrational number, which means it has infinite non-repeating decimal places. Therefore, we will not get an exact value but an approximation.

2. Compare each option numerically to approximate [tex]\(\sqrt{12}\)[/tex]:

- Option A: [tex]\(3.0\)[/tex]
- This is a simple approximation and can be validated quickly. [tex]\(3.0^2 = 9\)[/tex], which is not very close to 12.

- Option B: [tex]\(3.446\)[/tex]
- Calculate [tex]\(3.446^2\)[/tex]:
[tex]\[ (3.446)^2 \approx 11.868 \][/tex]
- This is closer to 12 but not quite there.

- Option C: [tex]\(3.46\)[/tex]
- Calculate [tex]\(3.46^2\)[/tex]:
[tex]\[ (3.46)^2 \approx 11.9716 \][/tex]
- This is a closer approximation but still not perfect.

- Option D: [tex]\(3.464\)[/tex]
- Calculate [tex]\(3.464^2\)[/tex]:
[tex]\[ (3.464)^2 \approx 11.999296 \][/tex]
- This is very close to 12.

3. After comparing the closeness of each square to 12, the value [tex]\(3.464\)[/tex] provides the closest squared result to 12.

Therefore, the most precise approximation of [tex]\(\sqrt{12}\)[/tex] from the given options is:
[tex]\[ \boxed{3.464} \][/tex]
