If fractions and decimals don't scare you, then there are an infinite number
of squares in any range.
If you only want to hear about whole numbers, then there are five squares
in that range:
22 = 4
32 = 9
42 = 16
52 = 25
62 = 36
There are 2 prime numbers between 30 and 40: 31 and 37.
There are 2*13 = 26 natural numbers between them.
37
The square root of 31 falls between the whole numbers 5 and 6.
2 5 7 11 13 17 29 37 41
Halfway between 37 and 143 is the mean average of 37 and 143: (37 + 143) ÷ 2 = 90
31 & 37
There are 2 prime numbers between 30 and 40: 31 and 37.
1 & 2
There are 2*13 = 26 natural numbers between them.
37

75 - 1 = 74 numbers between 1 and 75. Divide 74 by 2 = 37 even numbers.
2 5 7 11 13 17 29 37 41
There are 16 square numbers between 1 and 300: 2 to 17 inclusive. There is no square root of these numbers: only of their sum or product or average or some other operation.

Write both numbers as decimal numbers, then look for terminating decimals between the two.
