Question

Represente, em seu caderno, na forma de radical a) 2 2/3 b) 7 2/5 c) 8 1/2 d) 9 1/3

Answer 1

       $2^{ \frac{2}{3} } = \sqrt[3]{2^2} = \sqrt[3]{4}$

       $7^{ \frac{2}{5} } = \sqrt[5]{7^2}= \sqrt[5]{49}$

       $8^{ \frac{1}{2} } = \sqrt{8^1} = \sqrt{8}$

       $9^{ \frac{1}{3} }= \sqrt[3]{9^1} = \sqrt[3]{9}$
