(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Simplify

2. Relevant equations

[tex]\frac{\sqrt{a-\sqrt{a}}\times\sqrt{a+\sqrt{a}}}{\sqrt{a-1}}[/tex]

3. The attempt at a solution

[tex]\frac{\sqrt{(a-\sqrt{a})(a+\sqrt{a})}}{\sqrt{a-1}}[/tex]

[tex]\frac{\sqrt{a^2-a}}{\sqrt{a-1}} \times \frac{\sqrt{a-1}}{\sqrt{a-1}}[/tex]

[tex]\frac{\sqrt{(a^2-a)(a-1)}}{a-1}[/tex]

I'm not sure how to go from there, or if I did something wrong along the way. I just need that next step. thanks.
