I have tried everything I know, but I can't solve this. Can you please show me the right direction?
$\displaystyle \frac{16^\frac{1}{3}*4^\frac{1}{3}}{8}$
Thank you!
change the square root in the denominator to a power (you know how to do that, right? see my post here)
so we get $\displaystyle \frac{x^{2n+1}*x^\frac{1}{2}}{\sqrt{x^{3n}}} = \frac{x^{2n+1}*x^\frac{1}{2}}{x^\frac {3n}{2}}$
Now continue
