Which expression is equivalent to [tex]$\sqrt[3]{x^5 y}$[/tex]?

A. [tex]$x^{\frac{5}{3}} y$[/tex]
B. [tex]$x^{\frac{5}{3}} y^{\frac{1}{3}}$[/tex]
C. [tex][tex]$x^{\frac{3}{5}} y$[/tex][/tex]
D. [tex]$x^{\frac{3}{5}} y^3$[/tex]



Answer :

Sure! Let's analyze the expression [tex]\(\sqrt[3]{x^5 y}\)[/tex].

1. Understanding cube roots:
- The cube root of any expression [tex]\(\sqrt[3]{A}\)[/tex] can be written as [tex]\(A^{\frac{1}{3}}\)[/tex].

2. Apply the cube root:
- Given the expression [tex]\(\sqrt[3]{x^5 y}\)[/tex], we can rewrite this as [tex]\((x^5 y)^{\frac{1}{3}}\)[/tex].

3. Distribute the cube root exponent:
- When we have a product inside an exponent, we can apply the exponent to each individual factor inside the product:
[tex]\[ (x^5 y)^{\frac{1}{3}} = x^{5 \cdot \frac{1}{3}} \cdot y^{1 \cdot \frac{1}{3}} \][/tex]

4. Simplify the exponents:
- Simplify each exponent separately:
[tex]\[ x^{5 \cdot \frac{1}{3}} = x^{\frac{5}{3}} \][/tex]
[tex]\[ y^{1 \cdot \frac{1}{3}} = y^{\frac{1}{3}} \][/tex]

5. Combine the results:
- Putting it all together, we get:
[tex]\[ x^{\frac{5}{3}} y^{\frac{1}{3}} \][/tex]

Therefore, the expression [tex]\(x^{\frac{5}{3}} y^{\frac{1}{3}}\)[/tex] is equivalent to [tex]\(\sqrt[3]{x^5 y}\)[/tex].

So, the correct answer is:

[tex]\[ \boxed{x^{\frac{5}{3}} y^{\frac{1}{3}}} \][/tex]
