Question

How to simplify this expression

Answer 1

`\bf -\sqrt{\cfrac{1-(2)/(√(11))}{11}}\implies -\sqrt{\cfrac{~~(√(11)-2)/(√(11))~~}{(11)/(1)}}\implies -\sqrt{\cfrac{√(11)-2}{11√(11)}}`

I don't see it simplifying further, there are other ways that can change it to
`\bf -\sqrt{\cfrac{7}{121+22√(11)}}` , but that won't really be that simplified per se.
