    Hint: Multiply both the numerator and the denominator by √3.

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

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

    Yeah i meant what you said second... so would i have 24/9... with the square root of course.. but then would it be square root of 24 over 3?

    Yes but you can rewrite [tex] \sqrt{24} = a \sqrt{b} [/tex] What are a and b?
