    \[(\sqrt{x}-1/\sqrt{x})/(1-1\sqrt{x)}\]

    \[\frac{\sqrt{x}-\frac{1}{\sqrt{x}}}{1-\frac{1}{\sqrt{x}}}\] ?

    combine fractions on top first \[\sqrt{x} - \frac{1}{\sqrt{x}} = \frac{x-1}{\sqrt{x}}\]

    then combine fractions on bottom \[1-\frac{1}{\sqrt{x}} = \frac{\sqrt{x}-1}{\sqrt{x}}\]

    use rule when dividing fractions Flip and Multiply \[=\frac{x-1}{\sqrt{x}}*\frac{\sqrt{x}}{\sqrt{x}-1}\]

    sqrt(x) cancel remember \[x^{2} -1 = (x-1)(x+1)\] so \[x-1 = (\sqrt{x}-1)(\sqrt{x}+1)\]
