Which choice is equivalent to the product below?

[tex]\[ \sqrt{\frac{6}{8}} \cdot \sqrt{\frac{6}{18}} \][/tex]

A. [tex]\(\frac{7}{12}\)[/tex]

B. [tex]\(\frac{3}{4}\)[/tex]

C. [tex]\(\frac{6}{12}\)[/tex]

D. [tex]\(\frac{1}{4}\)[/tex]

E. [tex]\(\frac{7}{1}\)[/tex]



Answer :

Let's break down the given expression and find its equivalent value step by step:

1. Calculate the product of the square roots:
[tex]\[ \sqrt{\frac{6}{8}} \cdot \sqrt{\frac{6}{18}} \][/tex]

2. We know that the product of two square roots can be combined under a single square root:
[tex]\[ \sqrt{\frac{6}{8}} \cdot \sqrt{\frac{6}{18}} = \sqrt{\left(\frac{6}{8}\right) \cdot \left(\frac{6}{18}\right)} \][/tex]

3. Multiply the fractions inside the square root:
[tex]\[ \left(\frac{6}{8}\right) \cdot \left(\frac{6}{18}\right) = \frac{6 \cdot 6}{8 \cdot 18} = \frac{36}{144} \][/tex]

4. Simplify the fraction:
[tex]\[ \frac{36}{144} = \frac{1}{4} \][/tex]

5. Now, take the square root of the simplified fraction:
[tex]\[ \sqrt{\frac{1}{4}} = \frac{1}{2} \][/tex]

So, the product [tex]\(\sqrt{\frac{6}{8}} \cdot \sqrt{\frac{6}{18}} = \frac{1}{2}\)[/tex].

Now let's compare this result with the given choices:

- A. [tex]\(\frac{7}{12}\)[/tex]
- B. [tex]\(\frac{3}{4}\)[/tex]
- C. [tex]\(\frac{6}{12}\)[/tex] which simplifies to [tex]\(\frac{1}{2}\)[/tex]
- D. [tex]\(\frac{1}{4}\)[/tex]
- E. [tex]\(\frac{7}{1}\)[/tex]

From the above choices, it's clear that:
[tex]\[ \sqrt{\frac{6}{8}} \cdot \sqrt{\frac{6}{18}} = \frac{1}{2} \][/tex]

Thus, the equivalent choice is:
[tex]\[ \boxed{\frac{6}{12}} \][/tex]
which simplifies to [tex]\(\boxed{C}\)[/tex].
