Rewrite in simplest radical form x 5/6 x 1/6
Natasha_Volkova [10]

Answer:

x^{\frac{5}{6}}/x^{\frac{1}{6}} = \sqrt[3]{x^2}

Step-by-step explanation:

Given

x^{\frac{5}{6}}/x^{\frac{1}{6}}

Required

Rewrite in simplest radical form

Using laws of indices:

a^m/a^n = a^{m-n}

This implies that

x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{5}{6} - \frac{1}{6}}

Solve Exponents

x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{5 - 1}{6} }

x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{4}{6} }

Simplify exponent to lowest fraction

x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{2}{3} }

Using laws of indices:

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

This implies that

x^{\frac{5}{6}}/x^{\frac{1}{6}} = \sqrt[3]{x^2}

This is as far as the expression can be simplified
