Write with Rational (Fractional) Exponents ( cube root of 7^2)/( square root of 7)

$\frac{\sqrt[3]{7^{2}}}{\sqrt{7}}$

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{7^{2}}$ as $7^{\frac{2}{3}}$ .

$\frac{7^{\frac{2}{3}}}{\sqrt{7}}$

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{7}$ as $7^{\frac{1}{2}}$ .

$\frac{7^{\frac{2}{3}}}{7^{\frac{1}{2}}}$
