Question

I really need to know how to solve both please

Answer 1

13. An exponent in the form of $a^{\frac{2}{3}}$ is equivalent in saying $\sqrt[3]{a^{2}}$

So, we can apply that to our fraction:

$(\frac{64m^{6}}{27n^{9}})^{\frac{2}{3}} = \sqrt[3]{(\frac{64m^{6}}{27n^{9}})^{2}}$
$=\sqrt[3]{\frac{4096m^{12}}{729n^{18}}}$
$=\frac{16m^{4}}{9n^{6}}}$

14. Using the properties from the previous question, you should be able to complete this question. If you're having troubles, let me know and I'll walk you through it.
