You can't write that as an exact fraction. In general, the square root of a natural number is either a natural number, or an irrational number - i.e., one that can't be written as a fraction. Of course, you can approximate it; for example (as a mixed fraction) as 3 74/100, or as 3 3/4.
30. Square root is a number, times itself. 30x30 =900. Other examples of square root are 4x4=16, so 4 is the square root of 16. 5x5=25, so 5 is the square root of 25. 10 is the square root of 100, because 10x10=100.
