Answer
a) $2\sqrt 11$
b)$4$
c)$\frac{1}{4}$
Work Step by Step
a)$\frac{\sqrt {132}}{\sqrt 3}=\sqrt {44}=\sqrt 4\times\sqrt {11}=2\sqrt {11}$
b)$\sqrt[3] 2\sqrt[3] {32}=\sqrt[3] {2\times32}=\sqrt[3] {64}=4$
c)$\sqrt[4] {\frac{1}{4}}\sqrt[4] {\frac{1}{64}}=\sqrt[4] {\frac{1}{4}\times\frac{1}{64}}=\sqrt[4] {\frac{1}{256}}=\frac{1}{4}$
