30. The 3 is representing 3 * 101 which is equal to 30.

The largest 3 digit square number is 961 because 31*31 = 961
It is: 31*31 = 961
93
The smallest three-digit number is 100, and the largest is 999. The smallest integer whose square is a three-digit number is 10 (since (10^2 = 100)), and the largest integer is 31 (since (31^2 = 961)). Therefore, the three-digit perfect squares correspond to the integers from 10 to 31, which gives us a total of (31 - 10 + 1 = 22) three-digit perfect squares.
It is 231, exactly as in the question.A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 31,000,000,000.
The absolute value is a number's distance from zero on a number line. Therefore the absolute value of -31 is 31.

31 = 3 + 33 + (3/3).
