Answer 1

Take 1/x common

..then Rationalise the expression inside the bracket by { 3 +(9 - x)½ }

..after that put the value of x in the expression where it wont be able create anymore complexity...and finally you will get rid of x.

So the answer is 1/27

When you have to solve zero by zero form ..then factorisation ans rationalisation are the basic ways to solve them.
