acc to light,

If,a>b , b>c so c <a

but then sq root wont exist

so a=b=c shud be the case if no complex nos
so sq root is zero

no no.. this is not the way..

there is a final answer..

and if you look closely the given expression is already complex.. So the final answer will be a complex number but will not involve any i's [1]

Hint: try to observe something before jumping to attempt the question
