The two square roots used are 2 and 3, since 2 and 3 squared are 4 and 9, respectively. Since 5 is between 4 and 9, we can deduce that the square root of 5 is between 2 and 3.
The answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.

If you have a square root of a number, that means that your "square root" squared (multiplied by itself) will give you your original number. For example: * The square root of 4 is 2. * 2 x 2 is 4.
Of course not. 3 squared is 9, the square root of 9 is 3.
This is related to the technique used to eliminate square roots from the denominator. If, for example, the denominator is 4 + root(3), you multiply both numerator and denominator by 4 - root(3). In this case, "4 - root(3)" is said to be the "conjugate" of "4 + root(3)". When doing this, there will be no more square roots in the denominator - but of course, you'll instead have a square root in the numerator.
