Answer 1

Resposta:

$a) \sqrt{2x7} \\\sqrt{14}\\b) \sqrt[3]{5x10}\\\sqrt[3]{50} \\c)\sqrt[4]{6x2} \\\sqrt[4]{12} \\d) \sqrt{15x2}\\\sqrt{30} \\ e) \sqrt[3]{7x4}\\\sqrt{28}\\ f)\sqrt{15:3} \\\sqrt{5} \\\\ \\g) \sqrt[3]{20:2} \\\sqrt[3]{10}\\ h) \sqrt[4]{15:5}\\\sqrt[4]{3}\\ i) \sqrt{40:8} \\\sqrt{5}\\ j) \sqrt[3]{30:10} \\\sqrt[3]{3} \\k) \sqrt 2^{2} \sqrt{7}\\2\sqrt{7} \\\\l) \sqrt[3]{7x9}\\\sqrt[3]{63}$
