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: $\sqrt2 + 5i \text{ and } 6 + \sqrt5i$
