Which expression is equivalent to the radical expression shown below when it is simplified?

[tex]\[ \sqrt{\frac{3}{64}} \][/tex]

A. [tex]\(\frac{3}{64}\)[/tex]

B. [tex]\(\frac{\sqrt{3}}{8}\)[/tex]

C. [tex]\(\frac{3}{8}\)[/tex]

D. [tex]\(\frac{\sqrt{3}}{64}\)[/tex]



Answer :

To find which expression is equivalent to the given radical expression [tex]\(\sqrt{\frac{3}{64}}\)[/tex] when it is simplified, let's go through the steps of simplification.

1. Rewrite the Radical Expression:

The given expression is [tex]\(\sqrt{\frac{3}{64}}\)[/tex].

2. Apply the Property of Square Roots:

We can use the property of square roots that states:
[tex]\[ \sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}} \][/tex]
Applying this to our expression:
[tex]\[ \sqrt{\frac{3}{64}} = \frac{\sqrt{3}}{\sqrt{64}} \][/tex]

3. Simplify the Denominator:

Next, we simplify [tex]\(\sqrt{64}\)[/tex]. Since [tex]\(64\)[/tex] is a perfect square:
[tex]\[ \sqrt{64} = 8 \][/tex]
So, the expression now becomes:
[tex]\[ \frac{\sqrt{3}}{8} \][/tex]

4. Comparison to Options:

Having simplified the original expression to [tex]\(\frac{\sqrt{3}}{8}\)[/tex], we compare this to the given options:

- A. [tex]\(\frac{3}{64}\)[/tex]: This does not match [tex]\(\frac{\sqrt{3}}{8}\)[/tex].
- B. [tex]\(\frac{\sqrt{3}}{8}\)[/tex]: This matches our simplified expression.
- C. [tex]\(\frac{3}{8}\)[/tex]: This does not match [tex]\(\frac{\sqrt{3}}{8}\)[/tex].
- D. [tex]\(\frac{\sqrt{3}}{64}\)[/tex]: This does not match [tex]\(\frac{\sqrt{3}}{8}\)[/tex].

Therefore, the correct equivalent expression is:

[tex]\[ \boxed{\frac{\sqrt{3}}{8}} \][/tex]

So the correct answer is B. [tex]\(\frac{\sqrt{3}}{8}\)[/tex].
