Why must you not have a radical in the denominator? As you wrote the original expression, you indicated $$\frac{\sqrt{8}}{3}$$

Did you really mean to write $$\sqrt{\frac{8}{3}}$$ ? You can simplify this by multiplying by $$\frac{\sqrt{3}}{\sqrt{3}}$$, which is just a factor of 1.

Yes but you can rewrite $$\sqrt{24} = a \sqrt{b}$$ What are a and b?
