Which expression is equivalent to \root(3)(x^(5)y)
san4es73 [151]

Answer:

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

Step-by-step explanation:

Given

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

Required

The equivalent expression

We have:

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

Rewrite as an exponent

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

Open bracket

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

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