What is the perfect square factors for 50 times 90?
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.
Is 90 a square?

Is the different of the smallest three digit number and the smallest two digit number is a perfect square?
No. The smallest 2 digit number is 10 the smallest 3 digit number is 100 - so the question is whether (100-10) is a perfect square? No - 90 is not a perfect square. 8x8 is 64 and 9x9 is 91, not 90.
What is the probability that a randomly selected two-digit positive integer is a perfect square or a perfect cube?
There are 90 two-digit numbers from 10 to 99. Of those, 6 are perfect squares (16, 25, 36, 49, 64, and 81) and 2 are perfect cubes (27 and 64). Each perfect square or root has a probability of 1 in 90 in being drawn.
What is a perfect square and a perfect cube?
A perfect Square means a shape having 4 equal sides and the angle between two adjecent lines should be 90, But a perfect Cube means its an OBJECT with its four sides are equal dimentions. Any square has 4 equal sides and 90 degree corner angles. This is a question about number theory. A perfect square is a number whose square root is an integer (eg 9, 49 etc). Similarly a perfect cube is a number whose cube root is an integer (eg 8, 27 etc)
Is 200 a perfect square?
200 is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer.
