greater than
Yes, if the number is less than '1'.Just the opposite, if the number is greater than '1'.
x can be any number greater than 16 and less than 81.
Equal, because the square root of 100 is 10, and 20 halves is also 10.
Actually it can, if it's not the square of a prime number. For example, 144 is the square of 12; but you can also factor it as 6 x 24.

√3 = 1.732050808 Therefore, 0.85 is less than the square root of 3.
when the number is greater than 1
No there is not. If you are looking for prime factors of a number and you get to the square root of that number you can stop. Yes, there is. If an integer is not itself a prime, then one of its factors will be less or equal to its square root and the "co-factor" will be greater than or equal to the square root. But both cannot be greater than the square root so, when searching for factors, you can stop when you reach the square root.
