Select the correct answer:

Which expression is equivalent to [tex]\( \sqrt[3]{5} \)[/tex]?

A. [tex]\( \frac{3}{5} \)[/tex]
B. [tex]\( 5^3 \)[/tex]
C. [tex]\( \sqrt{5} \)[/tex]
D. [tex]\( \frac{5}{3} \)[/tex]

Sagot :

To determine which expression is equivalent to the cube root of 5, let's analyze each option step-by-step:

1. Option A: [tex]\(\frac{3}{5}\)[/tex]

- The fraction [tex]\(\frac{3}{5}\)[/tex] represents a division operation where 3 is divided by 5.
- This is clearly not equivalent to the cube root of any number.

2. Option B: [tex]\(5^3\)[/tex]

- The expression [tex]\(5^3\)[/tex] means 5 raised to the power of 3.
- Calculating this, we get [tex]\(5 \times 5 \times 5 = 125\)[/tex], which is not equivalent to the cube root of 5.

3. Option C: 51

- The number 51 is simply an integer.
- There is no mathematical relationship between 51 and the cube root of 5.

4. Option D: [tex]\(\frac{5}{3}\)[/tex]

- The fraction [tex]\(\frac{5}{3}\)[/tex] represents another division operation where 5 is divided by 3.
- This is also not equivalent to the cube root of 5.

Given these analyses, none of the provided options ([tex]\( \frac{3}{5}, 5^3, 51, \frac{5}{3} \)[/tex]) exactly match the cube root of 5, which is mathematically represented as [tex]\(5^{\frac{1}{3}}\)[/tex].

Therefore, none of the given options are equivalent to [tex]\(\sqrt[3]{5}\)[/tex]. The correct answer, in this case, is none of the provided choices.
