A square number is the product you get when you multiply a number by itself.
A square number is the product of a number and itself. 16 is square; it is the product of 4 and 4; 4 times 4.

The only three-digit number that fits the criteria of being a square number and having a product of its digits equal to two is 128. This is because 128 is a square number (11^2 = 121, 12^2 = 144) and the product of its digits (1 x 2 x 8) equals 16, which is not equal to two. Therefore, there is no three-digit number that meets all the given conditions.
121 121 = 11^2 1 x 2 x 1 = 2
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 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.
1225 = 352.

49Let's just try every square:12 = 122 = 432 = 9You could argue that any one of these answers the question, but the square number probably should have at least 2 digits:42 = 16; 1x6=6 ... no52 = 25; 2x5 = 10 ... no62 = 36; 3x6 = 18 ... no72 = 49; 4x9 = 36 = 62 ... yes!
