Which numbers create only rectangular arrays?
All integers that are not perfect squares.
Is square root are whole numbers?
Very rarely. Square roots are only whole numbers for perfect squares.
Do all square roots of perfect squares are rational numbers?
Yes. Not only that, they are counting numbers.
Which of the first ten perfect square numbers has only 3 factors?
Those would be the squares of prime numbers: 22, 32, 52, etc.
Rational numbers who square roots are whole numbers?
Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
Which numbers create only rectangular arrays?
All integers that are not perfect squares.
What are all the numbers that can be divided by only 3 multiples?
Numbers can't be divided by multiples. They get divided by factors. Factors go into numbers, numbers go into multiples.
Is square root are whole numbers?
Very rarely. Square roots are only whole numbers for perfect squares.
Do all square roots of perfect squares are rational numbers?
Yes. Not only that, they are counting numbers.
What multiples of 8 are perfect squares?
Multiples of 8 are numbers that can be expressed as 8n, where n is an integer. Perfect squares are numbers that are the result of multiplying an integer by itself, such as 1, 4, 9, 16, etc. To find which multiples of 8 are perfect squares, we need to find the numbers that can be expressed as 8n = m^2, where m is an integer. The only perfect square that is a multiple of 8 is 64, which is 8*8.
Which of the first ten perfect square numbers has only 3 factors?
Those would be the squares of prime numbers: 22, 32, 52, etc.
Is 31 a perfect number?
No. The only perfect numbers less than 100 are 6 and 28. All known perfect numbers are even - it is unknown whether there are odd perfect numbers.
What is the sum of all positive integers less than 100 that are squares of perfect squares?
The only squares of perfect squares in that range are 1, 16, and 81.
What numbers are between 3000 and 3200 that are perfect squares?
The square root of 3000 is 54.77 and the square root of 3200 is 56.57. So the only perfect squares in the required number range are 552 = 3025 and 562 = 3126.
Rational numbers who square roots are whole numbers?
Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
What are not perfect squares from 1 to 31?
The only perfect squares from 1 to 31 are 1, 4, 9, 16, and 25.All of the other 26 are NOT perfect squares.2,3,5,6,7,8,10,11,12,13,14,15,17,18,19,20,21,22,23,24,26,27.28,29,30,31
Are All square numbers even numbers?
No; most are not, not even close. 2 is not a square, 6 is not a square, 8 is not a square, 10 is not a square, 12 is not a square, and 14 is not a square, just for starters. Only a very small proportion of even numbers are squares: 4, 16, 36, 64, 100, 144, 196, 256, 324, 400....
