Which of the following is equal to the fraction below?

[tex]\left(\frac{4}{5}\right)^6[/tex]

A. [tex]6 \cdot\left(\frac{4}{5}\right)[/tex]

B. [tex]\frac{4^6}{5}[/tex]

C. [tex]\frac{4^6}{5^6}[/tex]

D. [tex]\frac{24}{30}[/tex]

Answer :

To find which option is equal to [tex]\(\left(\frac{4}{5}\right)^6\)[/tex], let's analyze each choice:

1. Calculating [tex]\(\left(\frac{4}{5}\right)^6\)[/tex]:

The expression [tex]\(\left(\frac{4}{5}\right)^6\)[/tex] means you multiply the fraction [tex]\(\frac{4}{5}\)[/tex] by itself 6 times. This results in:

[tex]\[
\left(\frac{4}{5}\right)^6 = \frac{4^6}{5^6}
\][/tex]

This is because when you raise a fraction to a power, you raise both the numerator and the denominator to that power.

- [tex]\(4^6 = 4096\)[/tex]
- [tex]\(5^6 = 15625\)[/tex]

So, [tex]\(\left(\frac{4}{5}\right)^6 = \frac{4096}{15625}\)[/tex].

2. Now, let's compare this with each option:

A. [tex]\(6 \cdot \left(\frac{4}{5}\right)\)[/tex]

- This expression is simply multiplying the fraction [tex]\(\frac{4}{5}\)[/tex] by 6, not raising it to the sixth power. It does not match [tex]\(\frac{4^6}{5^6}\)[/tex].

B. [tex]\(\frac{4^6}{5}\)[/tex]

- This would mean only the numerator (4) is raised to the sixth power, leaving the denominator as just 5, which is incorrect compared to [tex]\(\frac{4^6}{5^6}\)[/tex].

C. [tex]\(\frac{4^6}{5^6}\)[/tex]

- This exactly matches our calculated result.

D. [tex]\(\frac{24}{30}\)[/tex]

- This fraction simplifies to [tex]\(\frac{4}{5}\)[/tex] but not raised to any power. It does not match what we are looking for.

Therefore, option C. [tex]\(\frac{4^6}{5^6}\)[/tex] is the correct answer as it matches the original expression [tex]\(\left(\frac{4}{5}\right)^6\)[/tex].
