Square numbers of integers falling between 50 and 90 are: 82 = 64 92 = 81

140

There are an infinite list of different numbers, but only 90 of them are integers (whole numbers).

The greatest common factor of the numbers 90, 25 and 50 is 5.

The least common multiple of the numbers 50, 75 and 90 is 450.

They are: 9+81 = 90

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.

50-59 & 90-99.

89

To get square footage you multiply the width by the length. In this case 90 times 50 equals 4500 sq. feet

The perfect square factor of 50 is 25 and the perfect square factor for 90 is 9. The perfect square factors for 50x90 25x9. Of course we also have the other factors of 2 and 2x5.

90?

60 and 90 are the numbers between 50 and 100 that are factors of 180

3³ + 9² = 9 + 81 = 90.

The numbers given have no units so it is not possible to tell whether you mean 90 inches, 90 feet or 90 miles! Furthermore, the numbers are summed together. The sum of lengths remains a length, and cannot be expressed in square feet.The numbers given have no units so it is not possible to tell whether you mean 90 inches, 90 feet or 90 miles!

There are nine square numbers including 1 below 100 (1x1...9x9). So, there are 99 - 9 'not square numbers' below 100 which is 90
