Simplifying 192333\frac{\sqrt[3]{-192}}{\sqrt[3]{3}} and 324n742n34\frac{\sqrt[4]{324n^7}}{\sqrt[4]{2n^3}}

Further practice simplifying quotients of higher-order roots by combining them into a single radical using the Quotient Property of nnth Roots.

192333\frac{\sqrt[3]{-192}}{\sqrt[3]{3}}: Write as one radical: 19233\sqrt[3]{\frac{-192}{3}} Simplify the fraction: 643\sqrt[3]{-64} Simplify the perfect cube: 4-4

324n742n34\frac{\sqrt[4]{324n^7}}{\sqrt[4]{2n^3}}: Write as one radical: 324n72n34\sqrt[4]{\frac{324n^7}{2n^3}} Simplify the fraction: 162n44\sqrt[4]{162n^4} Rewrite using perfect fourth power factors: 81n424\sqrt[4]{81n^4 \cdot 2} Simplify the perfect fourth root. Since the index is even, absolute value is required for the variable: 3n243|n|\sqrt[4]{2}
