Question

Me ajudem! só péssimo em matemática.

Answer 1

$a)\sqrt{9^{2}} = 9\\\\b)\sqrt{8^{2}} = 8\\c)\sqrt[5]{2^{5}} = 2\\\\d)\sqrt{(\frac{5}{7})^{2}} = \frac{5}{7}\\ \\e)\sqrt[5]{(-2)^{5}} = -2\\\\f) \sqrt[3]{(\frac{4}{5})^{3}} = \frac{4}{5}\\g)\sqrt[5]{5^{5}} = 5\\\\h)\sqrt{9^{2} * 7} = 9\sqrt{7}\\\\i)\sqrt{6^{2} * 6^{2}} = 36\\\\j)\sqrt{4 * 5} = 2\sqrt{5}  \\\\k)\sqrt{3}{2^{3}} = 2\\\\l)\sqrt{2^{12}} = 2^{6} = 4^{3} = 64$
