    simplify

    how (-3) / [(3x-1)(sqrt 3x-1)] can simplified as -3(3x-1)^(-3/2) ?

    i don't understand because if you simplify -3(3x-1)^(-3/2), it would be (-3)/(3sqrt 3x-1) ???

    \frac{-3}{(3x-1)\sqrt{3x-1}}=\frac{-3}{\sqrt{3x-1}\sqrt{3x-1}\sqrt{3x-1}}=\frac{-3}{(\sqrt{3x-1})^3}

    =\frac{-3}{(3x-1)^{\frac{3}{2}}}=-3(3x-1)^{-\frac{3}{2}}
