Answer 2

Resposta:

$\sqrt{3} \times\sqrt{12} =\sqrt{3.12} =\sqrt{36} =6\\ \\ \sqrt{15} \times\sqrt{3} =\sqrt{15.3} =\sqrt{45} =\sqrt{3^2.5} =3\sqrt{5} \\ \\ 6\sqrt{7} \times7\sqrt{6} =6.7\sqrt{7.6} =42\sqrt{42} \\ \\7 \sqrt[3]{2} \times\sqrt[3]{16} \times\sqrt[3]{2} =7\sqrt[3]{2.16.2} =7\sqrt[3]{64} =7\sqrt[3]{2^3.2^3} =7.2.2=28\\ \\ \sqrt{98\times2} =\sqrt{196} =14\\ \\ \sqrt[5]{8.4} =\sqrt[5]{32} =\sqrt[5]{2^5} =2$
