    Radical Expression

    Hey guys, I got this problem on my math sheet and I have no idea if I did it right because it's the first time I see something with a division and two multiplications.



    Thanks,

    \frac{a}{b} \div \frac{c}{d} \ne \frac{b}{a} \times \frac{c}{d}<br />

    \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}<br />

    The answer you put is incorrect. It is the reciprocal of that.

    [Math]\frac{(2w-3)(2w+3)^2}{6}[/tex]

    You can test any simplification or expansion/contraction problem by assigning the variable an arbitrary value, then solve for the original equation and then your result.
