a)

[tex] \sqrt{27} = \sqrt{9 \times 3} = 3 \sqrt{3} [/tex]

b)

[tex] \sqrt{128} = \sqrt{64 \times 2} = 8 \sqrt{2} [/tex]

c)

[tex] \sqrt{75} = \sqrt{25 \times 3} = 5 \sqrt{3} [/tex]

d)

[tex] \sqrt[3]{81} = \sqrt[3]{3 \times 27} = 3\sqrt[3]{3 } [/tex]

e)

[tex] \sqrt[3]{2000} = \sqrt[3]{1000 \times 2} = 10 \sqrt[3]{2} [/tex]

f)
