Determine two complex numbers, (a+bi) and (c+di), where a and d are irrational numbers and b and c are rational number
Dafna11 [192]

Answer:

The two complex numbers are \sqrt2 + 5i \text{ and } 6 + \sqrt5i

Explanation:

We have to form two complex numbers of the form

a + ib\\c + id

such that and d are irrational numbers and b and c are rational numbers.

We know that \sqrt2, \sqrt3 are irrational numbers.

5 and 6 are rational numbers.

We put

a = \sqrt2\\b = 5\\c = 6\\d = \sqrt5\\a+ib = \sqrt2 + 5i\\c + id = 6 + \sqrt5i

Thus, the two complex numbers are: \sqrt2 + 5i \text{ and } 6 + \sqrt5i
