-10 or +10
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.
The numbers are: 26 -square root of 524 and 26 +square root of 524
If you have a data set, simply take the square root of the sum of the squares of the data points. Let's say you have three numbers a, b, and c. RSS = SQRT(a2 + b2 + c2).
The numbers are: 6 plus square root of 27 and 6 minus square root of 27
The four possible answers are +/- 18 or +/- 22.
It's not. Take 49 and 16 for example. The square root of the sum is the square root of 65. The sum of the square roots is 11.
There are 16 square numbers between 1 and 300: 2 to 17 inclusive. There is no square root of these numbers: only of their sum or product or average or some other operation.
The sum, or difference, of two irrational numbers can be rational, or irrational. For example, if A = square root of 2 and B = square root of 3, both the sum and difference are irrational. If A = (1 + square root of 2), and B = square root of 2, then, while both are irrational, the difference (equal to 1) is rational.
There are none but: (15+square root of 129)/2 and (15-square root of 129)/2 will give a sum of 15 and a product of 24
example for sum of rational numbers is 1/3 + 1/5 Example for sum of irrationals is Pi + e where e is is base of natural log Another is square root of 2 + square root of 3.
Both must be the positive square root of N.
