1. a)
[tex] \sqrt{2 \times 2 \times 5 \times 5} = \sqrt{4 \times 25} = \sqrt{100} = 10[/tex]
b)
[tex] \sqrt[3]{6 \times 6 \times 3 \times 3 \times 6 \times 3} = \sqrt[3]{27 \times 216} = \sqrt[3]{5832} = 18[/tex]
c)
[tex] \sqrt{ {5}^{2} \times {4}^{2} } = \sqrt{25 \times 16} = \sqrt{400} = 20[/tex]
d)
[tex] \sqrt[3]{ {2}^{3} \times {7}^{3} } = \sqrt[3]{8 \times 343} = \sqrt[3]{2744} = 14[/tex]
