The smallest square number qreater than 1 is 2. * * * * * 2 is not a perfect square number.
If the number is one, then it is the smallest positive square.
4, which is the square of the prime number 2, is the smallest composite number.
The number of digits in the square root of a number depends on the number. If it is a square number, the square root will have a finite number of digits. If the number is not a square number then the square root will be an irrational number with an infinite, non-repeating decimal representation. In both cases, the number of digits before the decimal point, in the square root of x will be the rounded value of 1+0.5*log10(x)
I cannot see how odd or even will determine the number of digits in the square root. For example:100 is an even number, and its square root is 10 (2 digits)121 is an odd number, and its square root is 11 (2 digits)Maybe the question is not phrased properly for what the questioner is asking.
The smallest perfect square is 121.
One possible answer is 1/2550, which will make the product 1: 1 is a perfect square. Alternately, you could try 102, but that is far from the smallest.
The square root of pi is an irrational number, meaning it has an infinite number of digits after the decimal point. It is typically rounded to a limited number of digits for practical use, such as 3.1416. However, if you are looking for the actual number of digits in the square root of pi, it would be infinite.
There are infinitely many possible answers. The smallest set of numbers is (9, 16, 144, 169)

1002 = 10000 which is the smallest possible 5 digit number. So we have to go 1 smaller which is 992 = 9801
