Question

Simplify : $2\sqrt[4]{481}-8\sqrt[3]{3216}+15\sqrt[5]{532}+\sqrt{225}-\sqrt[4]{416}$

• A. $0$
• B. $1$
• C. $-1$
• D. $2$

Answer 1

The correct option is B $1$

$2\sqrt[4]{481}-8\sqrt[3]{3216}+15\sqrt[5]{532}+\sqrt{225}-\sqrt[4]{416}2{\left(3^4\right)}^{\frac{1}{4}}-8{\left(6^3\right)}^{\frac{1}{3}}+15{\left(2^5\right)}^{\frac{1}{5}}+{\left({15}^2\right)}^{\frac{1}{2}}-{\left(2^4\right)}^{\frac{1}{4}}2\times \left(3\right)-8\left(6\right)+15\left(2\right)+15-26-48+30+15-2=1$
