The sum is rational.



The sum is 5 square root of 14



The sum is a real number.



The terms can be rewritten into simplest radical form so that each term has square root of 14 .

Respuesta :

The square root of 56 + the square root of 126 is 18.70828693. This is not a rational sum. You might ask how this number is a real number, and this is because irrational numbers fit under the category of real numbers. A non-real number, for example, would be the square root of -1 (which is i).
