First since I don't know how to type in the square root of something, I'm going to type it in like this: sqrt(x)
Now say you have 1/sqrt(3). The square root can not be on the bottom. So mulitply the equation by the sqrt(3). This means TOP and BOTTOM! so then it looks like sqrt(3)/3. And that is an acceptable answer.

The square roots of 13 cannot be simplified.
it depends on the numbers involved.. if you have examples of the fractions decimals and square roots i would be glad to help you
The square roots of 81 are integers, not fractions. So there are no sensible ways to express them as fractions.
In general, it's impossible to represent square roots as fractions of rational numbers; however, in the specific case of 9, it's a perfect square and the roots are 3 and -3. If you insist on fractions, 3/1 and -3/1.
Replace the radical sign with the exponent 0.5. For example sqrt(7) = 70.5
