Answer:

x^\frac{5}{3} y^\frac{1}{3}

Step-by-step explanation:

This question is on rules of rational exponential

where the exponential is a fraction, you can re-write it using radicals where the denominator of the fraction becomes the index of the radical;

<u>General expression </u>

a^\frac{1}{n} =\sqrt[n]{a}

Thus    \sqrt[3]{x} =x^\frac{1}{3}

 

<u>Applying the same in the question </u>

\sqrt[3]{x^5y} =x^\frac{5}{3} y^\frac{1}{3}

=x^\frac{5}{3} y^\frac{1}{3}

Answer: Second option

(x^5y)^{\frac{1}{3}} = x^{\frac{5}{3}}y^{\frac{1}{3}}

Step-by-step explanation:

By definition we know that:

a ^{\frac{m}{n}} = \sqrt[n]{a^m}

In this case we have the following expression

\sqrt[3]{x^5y}

Using the property mentioned above we can write an equivalent expression for \sqrt[3]{x^5y}

\sqrt[3]{x^5y} = (x^5y)^{\frac{1}{3}}

(x^5y)^{\frac{1}{3}} = x^{\frac{5}{3}}y^{\frac{1}{3}}

Therefore the correct option is the second option
