A)
$\sqrt[3]{5} \times \sqrt[3]{6} = \sqrt[3]{30}$
b)
$\sqrt{2} \times \sqrt{8} = \sqrt{16} = \sqrt{2^4} =2^2=4$
c)
$\sqrt{2} \times \sqrt{6} \times \sqrt{3} = \sqrt{36} =6$
d)
$\sqrt{5} \times \sqrt{10} = \sqrt{50} = \sqrt{2.5^2} =5 \sqrt{2}$
e)
$\sqrt[3]{4} \times \sqrt[3]{6} = \sqrt[3]{24} = \sqrt[3]{2^3.3} =2 \sqrt[3]{3}$
f)
$\sqrt{2} \times \sqrt[3]{5} = \sqrt[6]{2^3} \times \sqrt[6]{5^2} = \sqrt[6]{8.25} = \sqrt[6]{200}$
