$\sqrt[5]{16x ^{13}y^8}\times \sqrt[5]{4xyz ^{10}}$

o.k are u here?

3. anonymous

so you can look at the whole thin as being under the root

4. anonymous

one way that i tackle these problems is that i like to put the radical as fractions

5. anonymous

$\sqrt{a}=a ^{1/2}$

6. anonymous

in this case the nth root is 5, so it would be $a^{1/5}$
