Simplifying 500323\frac{\sqrt[3]{-500}}{\sqrt[3]{2}} and 486m1143m54\frac{\sqrt[4]{486m^{11}}}{\sqrt[4]{3m^5}}

Practice simplifying quotients of higher-order roots by applying the Quotient Property of nnth Roots in reverse to combine the expressions into a single radical before simplifying.

500323\frac{\sqrt[3]{-500}}{\sqrt[3]{2}}: Write as one radical: 50023\sqrt[3]{\frac{-500}{2}} Simplify the fraction: 2503\sqrt[3]{-250} Rewrite using perfect cube factors: (5)323\sqrt[3]{(-5)^3 \cdot 2} Split and simplify: 523-5\sqrt[3]{2}

486m1143m54\frac{\sqrt[4]{486m^{11}}}{\sqrt[4]{3m^5}}: Write as one radical: 486m113m54\sqrt[4]{\frac{486m^{11}}{3m^5}} Simplify the fraction: 162m64\sqrt[4]{162m^6} Rewrite using perfect fourth power factors: 81m42m24\sqrt[4]{81m^4 \cdot 2m^2} Because the index is even, extract the perfect fourth root with absolute value for the variable: 3m2m243|m|\sqrt[4]{2m^2}
