So what do you know about multiplying numbers with exponents?

One thing youshould know is that:
$$a ^ {\frac{m}{n}} = \sqrt[n] {a ^ m}$$
For example:
$$25 ^ {\frac{1}{2}} = \sqrt{25} = 5$$
$$5 ^ {\frac{3}{2}} = \sqrt{5 ^ 3} = \sqrt{125}$$.
Now what's:
$$8 ^ {\frac{2}{3}} \quad \mbox{and} \quad 9 ^ {\frac{1}{2}}$$?
Can you go from here? :)
