m_a_m_a [10]

Answer:

The sum of the complex numbers is 9+i\,7.

Explanation:

Let be u = 6 + i\,2 and v = 3 + i\,5, the sum of the complex number can be found by algebraic means. That is:

1) u = 6 + i\,2, v = 3 + i\,5 Given.

2) u+v = (6+i\,2)+(3+i\,5) Definition of addition.

3) u+v = (6+3) + (2\,i + 5\,i) Commutative and associative properties.

4) u+v = 9 + (2+5)\,i Definition of addition/Distributive property.

5) u + v = 9 + i\,7 Definition of addition/Commutative property/Result.

The sum of the complex numbers is 9+i\,7.
