Which of the following is equivalent to [tex][tex]$6^{2/5}$[/tex][/tex]?

A. [tex] \sqrt[5]{6^2} [/tex]

B. [tex] \left(6^{1/5}\right)^2 [/tex]

C. [tex] \left(\sqrt[5]{6}\right)^2 [/tex]

D. All of the above



Answer :

To solve the expression [tex]\(6^{2 / 5}\)[/tex], let's break it down step by step:

1. Understand the expression: We have a base of 6 raised to the power of [tex]\(\frac{2}{5}\)[/tex].

2. Fractional exponent concept: A fractional exponent indicates both a root and a power. Specifically, [tex]\(a^{m/n}\)[/tex] means:
- Take the [tex]\(n\)[/tex]-th root of [tex]\(a\)[/tex], and then
- Raise the result to the [tex]\(m\)[/tex]-th power, or
- Raise [tex]\(a\)[/tex] to the [tex]\(m\)[/tex]-th power, and then
- Take the [tex]\(n\)[/tex]-th root of that result.

3. In our expression [tex]\(6^{2/5}\)[/tex]:
- [tex]\(2/5\)[/tex] suggests taking the 5th root of 6 first, and then squaring the result, or
- Squaring 6 first and then taking the 5th root of that result.

4. Adjusted Calculation Steps:
- Let's suppose we first compute using the 5th root and then squaring the result:
[tex]\[ 6^{2/5} \][/tex]

5. Result: After appropriately using the above approach, the result of [tex]\(6^{2/5}\)[/tex] is approximately [tex]\(2.0476725110792193\)[/tex].

6. Final answer: Therefore, [tex]\(6^{2/5}\)[/tex] is equivalent to approximately [tex]\(2.0476725110792193\)[/tex].
