The rule you can use is that root(a) x root(b) = root(ab), or root(a) / root(b) = root(a/b). This rule works for real numbers, but if you ever have to handle complex numbers, it is no longer valid. In the case of real numbers, it also works with cubic roots, fourth roots, etc.
It can add, subtract, multiply, divide and do square roots.

In a way. You can multiply top and bottom by the square root of 2. This will not exactly make the expression simpler, but you'll get rid of the square root in the denominator (and transfer it to the numerator); this is considered to be the standard form for expressions which involve square roots. In other words, there should be no square roots in the denominator.
people i am stuck in the square roots. Can you help by giving me the steps.
Divide the square root by itself

You can combine square roots when you multiply or divide. For example: root(2) x root(3) = root(6). You cannot do the same for addition and subtraction. For example, root(2) + root(3) can't be simplified.
You don't need square roots for this, and there is no use for them in this context. You simply divide both sides of the equation by 2.You don't need square roots for this, and there is no use for them in this context.

Yes, sometimes you need to do that.
If you multiply it by itself you get 13. This is what square roots do!
