Calculate √0.111...11 (There are 100 1's after the decimal point).
What's under the radical is (1/9)*(1  10^(100))
sqrt(1/9) is obviously 1/3
The other factor, (1  10^100) can be written as
10^100  1

10^100
The denominator's square root is 10^50.
The numerator consists of 100 9's. I don't see a way of getting its square root.
