79 & 81, or any whole number from 1 to 79 with any whole number greater than 81.
Whole numbers between 10 and 100 using the digits 3, 1, and 8 are:13, 18, 31, 38, 81, and 83.13, 18, 31, 38, 81 and 83.
No. From 64 to 81 is a vast wasteland with no whole-number squares.
You use short division for decimals by whole numbers, then replace the decimal point in between the numbers, the answer is 15.0
