Ответ:

$\sqrt{20} \times \sqrt{5} = \sqrt{20 \times 5} = \sqrt{100} = 10$

$\sqrt[3]{100} \times \sqrt[6]{6400} = \sqrt[6]{ {100}^{2} } \times \sqrt[6]{6400} = \\ = \sqrt[6]{ {100}^{2} \times 6400} = \sqrt[6]{ {80}^{2} \times {100}^{2}} = \\ = \sqrt[6]{ {8000}^{2} } = \sqrt[3]{8000} = \sqrt[3]{ {20}^{3} } = 20$

$\sqrt{250} \times \sqrt{10} = \\ = \sqrt{25} \times \sqrt{10} \times \sqrt{10} = 5 \times 10 = 50$

$\sqrt[4]{500} \times \sqrt{128 \sqrt{5} } = \\ =\sqrt[4]{500} \times \sqrt[4]{( {128 \sqrt{5}) }^{2} } = \\ = \sqrt[4]{500 \times {128}^{2} \times 5 } = \sqrt[4]{40960000} = \\ = 80$
