A. [tex]2.6307 \ldots[/tex] an irrational number
B. [tex]2.8867 \ldots[/tex] an irrational number
C. 4.2974 . . . an irrational number
D. [tex]4.1569 \ldots[/tex] an irrational number



Answer :

To solve the problem of finding the product of [tex]\(\sqrt{12}\)[/tex] and [tex]\(\frac{5}{6}\)[/tex], we can break it down into a few straightforward steps:

1. Compute [tex]\(\sqrt{12}\)[/tex]:
[tex]\[ \sqrt{12} \approx 3.4641016151377544 \][/tex]
This value is already approximated for us.

2. Express the fraction [tex]\(\frac{5}{6}\)[/tex]:
[tex]\[ \frac{5}{6} \approx 0.8333333333333334 \][/tex]
This value is also given in a decimal form.

3. Find the product of these two numbers:
[tex]\[ \sqrt{12} \times \frac{5}{6} \approx 3.4641016151377544 \times 0.8333333333333334 \][/tex]
Performing this multiplication, we get:
[tex]\[ 3.4641016151377544 \times 0.8333333333333334 \approx 2.8867513459481287 \][/tex]

Hence, the product of [tex]\(\sqrt{12}\)[/tex] and [tex]\(\frac{5}{6}\)[/tex] is approximately [tex]\(2.8867513459481287\)[/tex].

#### Determine the Type of Number:
To determine the type of number, consider that:

- [tex]\(\sqrt{12}\)[/tex] is an irrational number because it cannot be expressed as a simple fraction.
- [tex]\(\frac{5}{6}\)[/tex] is a rational number because it is expressed as a fraction of integers.

When you multiply an irrational number by a rational number (non-zero and non-repeating), the result is typically an irrational number.

Given the numerical result, we can observe:

- [tex]\(2.8867 \ldots \)[/tex] appears to be a non-repeating, non-terminating decimal, which confirms it is an irrational number.

Thus, the correct answer to the question is:

[tex]\[ 2.8867 \ldots \text{ an irrational number} \][/tex]
