    Hi andyboy,

    This is correct. And to simplify...

    \frac{3}{\sqrt{3}}=\frac{3\sqrt{3}}{3}=\sqrt{3}

    The reason is

    \frac{3}{\sqrt{3}}=\frac{3}{\sqrt{3}}\ \frac{\sqrt{3}}{\sqrt{3}}

    since any non-zero number divided by itself is 1,
    and multiplying by 1 does not change a value, just it's form.
