I think you question ----> : if (a^2 + b^2)^1/2 = 613 than (a+b) is ?
Solution :- it can't possible to give unique solution of (a + b)
Because √(a² + b²) = 613 is a equation which has contained two variables a and b . You can say this question is not given sufficient data's .
well, you can get (a + b) , when value of ab is given.
Let ab = k
Then, √{(a + b)² - 2ab} = 613
(a + b)² - 2k = 613²
(a + b)² = +√(613² + 2k )
so, when ab is given you can get to solve it
