What number is a perfect square and the sum of 2 perfect squares?
25 = 9 + 16 There are many more sets like these. This one has the smallest numbers.
Can 2819 be expressed by the sum of 2 perfect squares?
no
Can 4003 be expressed by the sum of 2 perfect squares?
No. The closest integers which can are 4001 (= 40² + 49²) and 4005 (= 6² + 63²).
Can you write every integer as the sum of two nonzero perfect squares?
No.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theoremNo.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theoremNo.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theoremNo.First of all, you can't write negative numbers as sums of perfect squares at all - since all perfect squares are positive.Second, for natural numbers (1, 2, 3...) you may need up to 4 perfect squares: http://en.wikipedia.org/wiki/Lagrange's_four-square_theorem

What is the smallest negative perfect square that is divisible by the four smallest prime numbers?
Perfect squares are positive. A smallest negative number doesn't exist. The four smallest prime numbers are 2, 3, 5 and 7. The smallest perfect square would have to be 2^2 x 3^2 x 5^2 x 7^2 or 44,100
How many perfect squares are between 900-1000?
1900
What is the smallest prime number whose sum of its digits forms a number that is a perfect cube?
I think it will be 17. The sum of digits is 8, which is the cube of 2.

If the regression sum of squares is large relative to the error sum of squares is the regression equation useful for making predictions?
If the regression sum of squares is the explained sum of squares. That is, the sum of squares generated by the regression line. Then you would want the regression sum of squares to be as big as possible since, then the regression line would explain the dispersion of the data well. Alternatively, use the R^2 ratio, which is the ratio of the explained sum of squares to the total sum of squares. (which ranges from 0 to 1) and hence a large number (0.9) would be preferred to (0.2).
How many perfect squares are there between 35 and 111?
To find the perfect squares between 35 and 111, we need to determine the perfect squares closest to these numbers. The closest perfect squares are 36 (6^2) and 100 (10^2). The perfect squares between 36 and 100 are 49 (7^2), 64 (8^2), and 81 (9^2). Therefore, there are 4 perfect squares between 35 and 111: 36, 49, 64, and 81.
What do you call the squares of whole numbers?
The squares of whole numbers are called perfect squares. A perfect square is a number that can be expressed as the product of an integer multiplied by itself. For example, 1, 4, 9, 16, and 25 are perfect squares because they can be written as 1^2, 2^2, 3^2, 4^2, and 5^2, respectively.
What is the sum of the smallest prime number?
2
What are examples of perfect square roots?
Perfect square roots are the counting numbers {1, 2, 3, ...} The squares of the perfect square roots are the perfect squares, namely 1² = 1, 2² = 4, 3² = 9, etc.
