Question

Por favor preciso das contas e das respostas ;)

Answer 1

5) Mulyiplique os radicais e calcule as raízes:
a) $\sqrt{17} \cdot \sqrt{17} = \sqrt{17\cdot17} = \sqrt{289} =17$
b)$\sqrt{3} \cdot \sqrt{6} \cdot\sqrt{6} \cdot \sqrt{3} = \sqrt{3\cdot6\cdot6\cdot3} = \sqrt{324} =18$
6) Simplifique os radicais:
a) $\sqrt[5]{224} = \sqrt[5]{2^5\cdot7} =\sqrt[5]{2^5}\cdot\sqrt[5]{7} =2\sqrt[5]{7}$
b) $\sqrt{363} = \sqrt{121\cdot3} = \sqrt{121}\cdot \sqrt{3} =11 \sqrt{3}$
