Eu consegui resolver a 6º)
a) \sqrt{6*24} = \sqrt{144} =12
b) \sqrt[3]{9*3} = \sqrt[3]{27} = \sqrt[3]{ 3^{3} } = 3
c) \sqrt{2*5*10} = \sqrt{100} =10
d) \sqrt{ \frac{48}{3} } = \sqrt{16} = 4
e) \sqrt[4]{ \frac{162}{2} } = \sqrt[4]{81} = \sqrt[4]{ 3^{4} } = 3
f) \frac{ \sqrt{3*12} }{ \sqrt[3]{2*4} } = \frac{ \sqrt{36} }{ \sqrt[3]{8} } = \frac{ \sqrt{ 6^{2} } }{ \sqrt[3]{ 2^{3} } } = \frac{6}{2} = 3
