Answer
a) $8\sqrt 5$
b)$3$
c)$5$ $\sqrt[3] 9$
Work Step by Step
a)$\sqrt 10\sqrt {32}=\sqrt {10\times32}=\sqrt {320}=\sqrt {64}\times\sqrt 5=8\sqrt 5$
b)$\frac{\sqrt {54}}{\sqrt 6}=\sqrt 9=3$
c) $\sqrt[3] 15$ $\sqrt[3] 75$ $=$ $\sqrt[3]5\times3\times\times5\times5\times3$ $=$ $\sqrt[3]5\times5\times\times5\times3\times3$ = $5$ $\sqrt[3] 9$
