Among the whole numbers, these are:149162536496481100

25 and 4 or 121 and 100
02 + 02 = 0; all other numbers squared are greater than 0. Otherwise 25 (= 52) = 32 + 4262 + 82 = 100√100 = 10; √1000 ≈ 31.6, so largest square less than 1000 is 312Between 100 and 1000 there are 31-10 = 21 square numbers (22 if 100 itself is included since 100 = 102)
100
There are nine square numbers including 1 below 100 (1x1...9x9). So, there are 99 - 9 'not square numbers' below 100 which is 90
There are 10 square numbers

Both 25 and 4 are factors of 100 and are square numbers, 25 is 52 and 4 is 22. 100 and 1 are also factors of 100, and are also square numbers: 1 is 12 and 100 is 102.
Among the whole numbers, these are:149162536496481100
There are 10 square numbers from 1 to 100, so the median is the mean average of the middle two - the 5th and 6th square numbers = (25 + 36) ÷ 2 = 30.5
