Answer:

8 $\sqrt{2}$

Step-by-step explanation:

Rationalise the denominator by multiplying both the numerator and denominator by the radical on the denominator, that is

$\frac{32}{\sqrt{8} }$

= $\frac{32\sqrt{8} }{8 }$ → ( $\sqrt{8}$ )² = 8

= $\frac{32\sqrt{4(2)} }{8}$

= 4× 2 $\sqrt{2}$

= 8 $\sqrt{2}$
