There are two, 64 and 81.
The first is 8 squared and the second is 9 squared. 10 squared is too much and 7 squared is too little.
64 and 81 are squares of whole numbers. 64 is the square of 8 (8x8=64) and 81 is the square of 9 (9x9=81).
83+7=90
89
The square numbers between 40 and 90 are: 49, 64, 81. This is because 7 squared = 49. 8 sqd. = 64. 9 sqd. = 81.
They are 25, 36, 49, 64, and 81 .
Square numbers of integers falling between 50 and 90 are: 82 = 64 92 = 81
140
92
There are an infinite list of different numbers, but only 90 of them are integers (whole numbers).
They are: 9+81 = 90
The greatest common factor of the numbers 90, 25 and 50 is 5.
64 and 81 are squares of whole numbers. 64 is the square of 8 (8x8=64) and 81 is the square of 9 (9x9=81).

Yes, in so far as all numbers are squares (of some number). But 90 is not a perfect square.
the only factors of 180 greater than 50 but least than 100 is 60 and 90 =)
They are: 43+47 = 90
83+7=90
