Which of the following is equivalent to [tex]$9^{\frac{1}{4}}$[/tex]?

A) [tex]$\sqrt[3]{9}$[/tex]
B) [tex][tex]$\sqrt[4]{9}$[/tex][/tex]
C) [tex]$\sqrt{3}$[/tex]
D) [tex]$3 \sqrt{3}$[/tex]



Answer :

To solve the expression [tex]\(9^{\frac{1}{4}}\)[/tex], we need to find the value of this fourth root.

The expression [tex]\(9^{\frac{1}{4}}\)[/tex] indicates the fourth root of 9. We want to find what this value is and which of the multiple choice options it equals.

### Step-by-Step Solution:

1. Understand the Power and Root Relationship:
- [tex]\(9^{\frac{1}{4}}\)[/tex] means [tex]\( \sqrt[4]{9} \)[/tex].

2. Simplify Under the Root:
- 9 can be expressed as [tex]\(3^2\)[/tex].
- Therefore, [tex]\(9^{\frac{1}{4}}\)[/tex] becomes [tex]\((3^2)^{\frac{1}{4}}\)[/tex].
- Using the power rule [tex]\((a^m)^n = a^{m \cdot n}\)[/tex], we get [tex]\(3^{2 \cdot \frac{1}{4}} = 3^{\frac{1}{2}}\)[/tex].

3. Understand What [tex]\(3^{\frac{1}{2}}\)[/tex] Represents:
- [tex]\(3^{\frac{1}{2}}\)[/tex] is the square root of 3, or [tex]\(\sqrt{3}\)[/tex].

Given these calculations, the answer is:

[tex]\[ 9^{\frac{1}{4}} = \sqrt{3} \][/tex]

### Comparing to Options:

Now let's compare to the given options:
- A) [tex]\(\sqrt[3]{9}\)[/tex]: This is the cube root of 9, which does not match our result.
- B) [tex]\(\sqrt[4]{9}\)[/tex]: This is equivalent to [tex]\(9^{\frac{1}{4}}\)[/tex], but not in a simplified form.
- C) [tex]\(\sqrt{3}\)[/tex]: This matches our simplified result, as we have shown [tex]\(3^{\frac{1}{2}} = \sqrt{3}\)[/tex].
- D) [tex]\(3 \sqrt{3}\)[/tex]: This represents three times the square root of 3, which is not correct.

Therefore, the correct option is:

[tex]\[ \boxed{C} \][/tex]
