Question

Which expression is equivalent to ^3√x^5y?a)x5/3b)x5/3y1/3c)x3/5 yd)x3/5 y3​

Answer 1

Answer:

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

Step-by-step explanation:

We are given our expression as

$\sqrt[3]{x^5y}$

The property of exponent says that

$\sqrt[n]{x} =x^{\frac{1}{n}}$

Hence

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

Another property says

$(ab)^n=a^n \times b^n$

Hence

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

Hence option B is correct.
