1, 4, 9, 16, 25, 36, 49, 64, 81 .
No square number is a prime number, since it has the number you squared as a factor. There are several square numbers less than 100. Just calculate the squares of all numbers, starting with 1, until you reach or pass 100. Then stop.
81 is the largest square of a whole number...
9 is an odd square number less than 10 and 92 = 81 which is greater than 50
9. The square root of 81 is 9.

Try the square roots of 1 and 6561, which are 1 and 81. Their difference is 80 which is one less than 81. And that is the square of 9. In fact this works whenevr the first of the two numbers is a square number. So the purpose of the question is not clear.

There are 10 numbers less than 101 which have an odd number of factors: 1,4,9,16,25,36,49,64,81,100.
0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144
0 1 4 9 16 25 36 49 64 81 100 121 144 169 196
x can be any number greater than 16 and less than 81.
81 is the largest square of a whole number...
9 is an odd square number less than 10 and 92 = 81 which is greater than 50
Squares numbers are positive numbers. So that the square numbers less than 100 are 1, 4, 9, 16, 25, 36, 49, 64, and 81, and only 16 and 64 are multiples of 8. Thus, Greta picked 16, and 64.
